dev-util/guile-1.6.4-r1 needs several patches to make it compile and install cleanly on macos. The first symptom is "gc_os_dep.c:380: error: parse error before '--' token". gc_os_dep.c is full of "#if defined(...)" statements designed to identify the OS that guile is being compiled on and then create some #defines to describe that OS's particular stack behavior. The #ifdef's don't properly recognize OS X. The solution is to add '-Dmacosx' to CFLAGS; this triggers the proper #define's in gc_os_dep.c and several other source files. After gc_os_dep.c is taken care of, the next problem is an "ld: Undefined symbols: _environ" error during linking. It seems that on OS X, the _environ symbol (which lives in /usr/lib/crt1.o) is only available to programs, not to shared libraries. Here it seems that adding the options "-flat_namespace -undefined suppress" to the linking step is the way to go: this suppresses the errors about undefined symbols during linking, deferring the symbol resolution to runtime. And at runtime, /usr/lib/crt1.o will be available to the executable; problem solved. The next, and most irritating, problem was a libtool quirk. Guile has two libraries, libguile and libguile-ltdl. When the .dylib files are built, they're kept in the libguile/.libs and libguile-ltdl/.libs directories respectively. But during the install phase, after libguile-ltdl is installed into /var/tmp/portage/guile-1.6.4-r1/image//usr/lib/, libtool thinks it should be looking in /usr/lib for it instead of /var/tmp/portage/(etc). And thus it fails to install libguile properly after installing libguile-ltdl. This caused me many, *many* hours of frustration peering at libtool internals. What finally worked was a patch from DarwinPorts (thanks, DarwinPorts folks!) that actually *downgrades* the included ltmain.sh in the guile distribution. It includes ltmain.sh version 1.4.3, but the patch downgrades it to 1.4.2. I don't know exactly what changed between these versions, but that works. That was all that was needed to make guile compile and run. There was one final patch from DarwinPorts that I also used, which patched the posix.c file to make the putenv function work properly. (putenv "foo=bar") worked as designed, but (putenv "foo") would fail with a "file not found" error. That form of putenv, (putenv "foo") with no equal sign in the parameter, is supposed to remove the variable "foo" from the process environment. The DarwinPorts patch makes that happen correctly. Finally, credit where credit is due: the hard work that the DarwinPorts folks put into solving these problems some time ago meant that I actually had a solution available when I needed it. Three cheers for DarwinPorts! Huzzah! Reproducible: Always Steps to Reproduce: 1. emerge -av guile. Fails. 2. Tweak ebuild to include several patches from DarwinPorts. 3. emerge -av guile.

Created attachment 38521 [details, diff] guile-macos-configure.patch Here's the patch that takes care of the dynamic library linking issue.
Created attachment 38522 [details, diff] guile-macos-ltmain.patch Here's the patch (from DarwinPorts) to downgrade ltmain.sh.
Created attachment 38523 [details, diff] guile-macos-posix.patch Here's the patch to posix.c to correct the putenv behavior.
Created attachment 38524 [details, diff] guile-1.6.4-r1.ebuild.patch Here's a patch to make the existing guile-1.6.4-r1 ebuild compile and work on macos. That's the last of the patches needed to make things work for me.
Depends on design issue 65272 - Marked as patch included
Applied slightly modified patches and committed. Thanks!
When will this patched version appear in portage? At the moment it still breaks with de gc_os_dep.c error.
It is avaiable at the moment. Please run `emerge sync` and try again.

Guile has always depended on readline, which is by default not available on OSX. masking guile and it's use flag for OSX
