It looks like something in the vim configuration is finding /usr/local/lib. I have a custom debug version of python installed under /usr/local (it may also have some other compile-time options that makes it incompatible with the gentoo installed version I have in /usr/). It appears that it is trying to link with my custom libpython2.3.so in /usr/local/lib: I've tried the emerge with sudo and 'su -'. I have no references to /usr/local in my environment during the emerge (no LD_LIBRARY_PATH either). The question is: why is it adding -L/usr/local/lib? Shouldn't it leave /usr/local alone? As a workaround, I temporarily moved /usr/local to /usr/local_tmp and the emerge worked fine. Reproducible: Always Steps to Reproduce: 1. Manually compile and install custom version of python under /usr/local along with gentoo version under /usr? 2. emerge =app-editors/vim-6.3-r2 Actual Results: make[2]: Leaving directory `/var/tmp/portage/vim-6.3-r2/work/vim63/src/po' gcc -c -I. -Iproto -DHAVE_CONFIG_H -O2 -march=athlon-xp -pipe -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/perl5/5.8.5/i686-linux/CORE -I/usr/include/python2.3 -pthread -I/usr/lib/ruby/1.8/i686-linux version.c -o objects/version.o gcc -rdynamic -rdynamic -L/usr/local/lib -o vim objects/buffer.o objects/charset.o objects/diff.o objects/digraph.o objects/edit.o objects/eval.o objects/ex_cmds.o objects/ex_cmds2.o objects/ex_docmd.o objects/ex_eval.o objects/ex_getln.o objects/fileio.o objects/fold.o objects/getchar.o objects/if_cscope.o objects/if_xcmdsrv.o objects/main.o objects/mark.o objects/memfile.o objects/memline.o objects/menu.o objects/message.o objects/misc1.o objects/misc2.o objects/move.o objects/mbyte.o objects/normal.o objects/ops.o objects/option.o objects/os_unix.o objects/pathdef.o objects/quickfix.o objects/regexp.o objects/screen.o objects/search.o objects/syntax.o objects/tag.o objects/term.o objects/ui.o objects/undo.o objects/window.o objects/if_perl.o objects/if_perlsfio.o objects/if_python.o objects/py_config.o objects/if_ruby.o objects/netbeans.o objects/version.o -lnsl -lncurses -lacl -lattr -lgpm -ldl -rdynamic -L/usr/local/lib /usr/lib/perl5/5.8.5/i686-linux/auto/DynaLoader/DynaLoader.a -L/usr/lib/perl5/5.8.5/i686-linux/CORE -lperl -lpthread -lnsl -ldl -lm -lcrypt -lutil -lc -L/usr/lib/python2.3/config -lpython2.3 -lpthread -ldl -lutil -lm -Xlinker -export-dynamic -lruby18 -ldl -lcrypt -lm objects/if_python.o(.text+0x1d4f): In function `PythonMod_Init': : undefined reference to `Py_InitModule4' objects/py_config.o(.data+0x44): undefined reference to `initxxsubtype' collect2: ld returned 1 exit status make[1]: *** [vim] Error 1 make[1]: Leaving directory `/var/tmp/portage/vim-6.3-r2/work/vim63/src' make: *** [first] Error 2 Expected Results: 1. don't add -L/usr/local/lib in link stage 2. don't look in /usr/local for anything!

Hrm, is vim the only package that does this? Not sure whether this is a general autoconfism or something strange vim is doing.
It looks like the auto-generated configure script tests for the presence of /usr/local/lib and adds it to LDFLAGS if it exists: (snagged from /var/tmp/portage/vim-6.3-r2/work/vim63/src/auto/configure) if test -z "$have_local_lib" -a -d /usr/local/lib; then tt=`echo "$LDFLAGS" | sed -e 's+-L/usr/local/lib ++g' -e 's+-L/usr/local/lib$++g'` if test "$tt" = "$LDFLAGS"; then LDFLAGS="$LDFLAGS -L/usr/local/lib" fi fi Thats as far as I've got in my digging... I don't know autoconf. Is configure.in the master?
I haven't _noticed_ any other package trying to link with stuff I have in /usr/local/lib. In my case, the error occurs because of a mismatch of the headers and library: -I/usr/include/python2.3 vs. -L/usr/local/lib.

I understand that it might be desirable to link against the /usr/local version, however it's not doing that correctly either, at least in the case of USE="python". If it's going to use the python in /usr/local, it should be using the python installed in /usr/local/bin to obtain the build flags (such as -I/usr/local/include/python2.3). What seems to be happening with vim is: the configure script notices that /usr/local/lib exists, and adds -L/usr/local/lib to the LDFLAGS, but it's using the /usr version of python to get the python (module?) build flags (notice the -I/usr/include/python2.3 in my compile output).
I'm going to close this one as WONTFIX. Looks like this is an autoconf feature.
