[gentoo-dev] portage compile problem (xemacs)

[Dave Lee]

So I was trying to compile xemacs and ./configure failed, here is there
error message

[snip]
checking for dbm_open in -lgdbm... no
Error: Required GNU DBM support cannot be provided.

!!! ERROR: The ebuild did not complete successfully.
[snip]

I do have gdbm, though

mj xemacs # qpkg -f /usr/lib/libgdbm.so
sys-libs/gdbm-1.8.0-r4 *

when I look in 
/var/tmp/portage/xemacs-21.1.14/work/xemacs-21.1.14/config.log
it seems that gcc is only being passed -L/usr/X11R6/lib so I assume this
is why ./configure cant find "dbm_open in -lgdbm"

why is this happening?  why cant portage find libgdbm?  I tried editing 
the xemacs ebuild file to remove the gdbm option to ./configure but then
./configure failes when looking for dl_open and says the C compiler is
broken.

any help is much appreciated.
