# FIXME: Maybe Perl, SDL, libpng.  Probably significant amount of

# FIXME: Install in a fresh Gentoo install to catch additional dependencies.
# FIXME: Remove conflict with non-CVS chandler builds
#
# Really should depend on gcc with the gcj use flag set, but
# apparently not possible to specify that condition here.
