I ran into exactly the same problem when I tried to install florist
under Red Hat 5. Ted Baker said he might possibly put up a new release
with better signal support this week. Let's hope he has the time to

(dreaming of the day when /usr/lib/libgnat.so and /usr/lib/libflorist.so
come as commonly preinstalled with every Linux distribution as libc,
in order to ensure portability of tiny Ada executables.
