I tried compiling from CVS but some libraries are apparently missing:

gcc -c -Wall -DVOL=volatile -fsigned-char -pipe -O3 -fomit-frame-pointer  
-I/home/neuss/CL-HOME/gcl/o -I../h -I../gcl-tk fat_string.c  
fat_string.c:17:17: bfd.h: No such file or directory
fat_string.c:18:21: bfdlink.h: No such file or directory
...

I guess I should wait for the Debian package.

Hmm, I actually like this self-contained setup for small packages.
Therefore I want to leave it as it is.  Testing Femlisp/GCL should work
anyway (maybe slightly more uncomfortably), only reloading binaries into a
fresh GCL would not work.

The Femlisp port to GCL is not very high-priority for me, although it would
be nice to have it working.  I will try out new GCL features as they arrive
and report to this list at which point the port hangs.  I guess that this
is the most fruitful approach for both parties.

Yours, Nicolas.
