Hey, that helped a lot!  I compiled it like this:

% gcc -fpic -DPIC -c module.c -o module.lo
% gcc -shared module.lo -o module.so

and it now runs, but dies within g_module_open.

% gdb min2
(gdb) b main
(gdb) r

I must say that this quiet but horrible death within gmodule-dl.c/
_g_module_open() is quite confusing.

I am going to follow Elliot's advice and upgrade my system to see if
that helps.
