It is not clear to me what package this bug is filed for. Please add more specific information to your bug, consider rewriting the subject the line and then reopen your report so it can be considered by the bug wranglers again. *** Bug 259935 has been marked as a duplicate of this bug. *** Current scm ebuild builds scm with two features: macro and inexact.
The defined scm features are:
array
Alias for ARRAYS
array-for-each
array-map! and array-for-each (arrays must also be featured).
arrays
Use if you want arrays, uniform-arrays and uniform-vectors.
bignums
Large precision integers.
byte
Treating strings as byte-vectors.
byte-number
Byte/number conversions
careful-interrupt-masking
Define this for extra checking of interrupt masking and some simple checks for proper use of malloc and free. This is for debugging C code in `sys.c', `eval.c', `repl.c' and makes the interpreter several times slower than usual.
cautious
Normally, the number of arguments arguments to interpreted closures (from LAMBDA) are checked if the function part of a form is not a symbol or only the first time the form is executed if the function part is a symbol. defining `reckless' disables any checking. If you want to have SCM always check the number of arguments to interpreted closures define feature `cautious'.
cheap-continuations
If you only need straight stack continuations, executables compile with this feature will run faster and use less storage than not having it. Machines with unusual stacks need this. Also, if you incorporate new C code into scm which uses VMS system services or library routines (which need to unwind the stack in an ordrly manner) you may need to use this feature.
compiled-closure
Use if you want to use compiled closures.
curses
For the curses screen management package.
debug
Turns on the features `cautious' and `careful-interrupt-masking'; uses -g flags for debugging SCM source code.
differ
Sequence comparison
dont-memoize-locals
SCM normally converts references to local variables to ILOCs, which make programs run faster. If SCM is badly broken, try using this option to disable the MEMOIZE_LOCALS feature.
dump
Convert a running scheme program into an executable file.
dynamic-linking
Be able to load compiled files while running.
edit-line
interface to the editline or GNU readline library.
engineering-notation
Use if you want floats to display in engineering notation (exponents always multiples of 3) instead of scientific notation.
generalized-c-arguments
make_gsubr for arbitrary (< 11) arguments to C functions.
i/o-extensions
Commonly available I/O extensions: exec, line I/O, file positioning, file delete and rename, and directory functions.
inexact
Use if you want floating point numbers.
lit
Lightweight -- no features
macro
C level support for hygienic and referentially transparent macros (syntax-rules macros).
mysql
Client connections to the mysql databases.
no-heap-shrink
Use if you want segments of unused heap to not be freed up after garbage collection. This may increase time in GC for *very* large working sets.
none
No features
posix
Posix functions available on all Unix-like systems. fork and process functions, user and group IDs, file permissions, and link.
reckless
If your scheme code runs without any errors you can disable almost all error checking by compiling all files with `reckless'.
record
The Record package provides a facility for user to define their own record data types. See SLIB for documentation.
regex
String regular expression matching.
rev2-procedures
These procedures were specified in the Revised^2 Report on Scheme but not in R4RS.
sicp
Use if you want to run code from: Harold Abelson and Gerald Jay Sussman with Julie Sussman. Structure and Interpretation of Computer Programs. The MIT Press, Cambridge, Massachusetts, USA, 1985. Differences from R5RS are:
* (eq? '() '#f)
* (define a 25) returns the symbol a.
* (set! a 36) returns 36.
single-precision-only
Use if you want all inexact real numbers to be single precision. This only has an effect if SINGLES is also defined (which is the default). This does not affect complex numbers.
socket
BSD socket interface. Socket addr functions require inexacts or bignums for 32-bit precision.
tick-interrupts
Use if you want the ticks and ticks-interrupt functions.
turtlegr
Turtle graphics calls for both Borland-C and X11 from sjm@ee.tut.fi.
unix
Those unix features which have not made it into the Posix specs: nice, acct, lstat, readlink, symlink, mknod and sync.
wb
WB database with relational wrapper.
windows
Microsoft Windows executable.
x
Alias for Xlib feature.
xlib
Interface to Xlib graphics routines.

patch that adds use flags for almost every scm feature
This patch lets you build scm-5.5.5-r1 with any feature you want. There were some features that gave me some errors. As commented in the ebuild:
# Some features give errors, here's a detailed list:
# mysql --> ERROR: database.c not found
# dynamic-linking --> It hasn't been implemented
# caution --> Causes errors
# edit-line --> Dependency problem with ltermcap
# reckless --> repl.c and eval.c doesn't build with this feature
# wb --> It gives these errors:
# gcc: db.o: No such file or directory
# gcc: wbsys.o: No such file or directory
# gcc: stats.o: No such file or directory
# gcc: segs.o: No such file or directory
# gcc: scan.o: No such file or directory
# gcc: prev.o: No such file or directory
# gcc: handle.o: No such file or directory
# gcc: ents.o: No such file or directory
# gcc: del.o: No such file or directory
# gcc: blkio.o: No such file or directory
# gcc: blink.o: No such file or directory
I've tested building every feature, but as usual it's better if someone else gives it a try.
