gentoo's "profile.env" is setting CPATH='/usr/include/libffi'
so it is finding the libffi headers, but gnustep's configure doesn't check if 
it can actually link to libffi or libffcall.. 
only that the headers are there.. 

attached to this is a patch, but i think i'm running the wrong autoconf to 
regenerate it for cvs.

Summary:  ./configure meaningless error or similar

Original Submission:  While running ./configure on a very recent gnustep-base 
(grabbed with cvs a couple of hours ago) I had this error:

checking for callback.h... no
checking "for forwarding callback in runtime"... yes
checking "FFI library usage"... libffi
checking for xml2-config... /usr/bin/xml2-config
checking for libxml - version >= 2.3.0... no
*** Could not run libxml test program, checking why...

You most likely do not want to build base without XML support.
For instance, MacOS-X compatible property lists require XML.
If you really want to build -base without XML support, add --disable-xml
to the configure arguments.
configure: error: Missing support for XML functionality.
pupeno@lab base $

I'm currently running gentoo and there's nothing with my xml, and in fact, the 
problem is with libffi, which is installed in /usr/lib/libffi/ and 
/usr/include/libffi. Maybe that's not nice and the ./configure script can't 
detect it, but even then, the error should be more accurte.

After running the following command, it worked:
$ ./configure --with-ffi-include=/usr/include/libffi/ --with-ffi-library=/usr/l
ib/libffi/

Thank you.
