Good question. The GNAP process calls Catalyst's GRP process, which in
turn uses "emerge" to compile and package the thing. I suspect it's not
GNAP- or Catalyst-specific, but rather a problem with the ebuild in the
specific build environment (minimal uclibc system).

You can try to emerge it manually using :
# chroot /var/tmp/catalyst/tmp/gnap/grp-x86-20050912/ /bin/bash
# emerge fbi
# exit

and see if you can reproduce the error... If you do, the problem is in
the ebuild/uclibc-env compatibility...
