Here is what I do:

% gcc -O2 -fno-common -c -o lbitlib.o lbitlib.c
% gcc -bundle -undefined dynamic_lookup -o bit.so lbitlib.o

More info under 'Building Modules: Mac OS X bundles':

Copy the 'bit.so' somewhere in 'package.cpath':

./?.so;/usr/local/lib/lua/5.1/?.so;/usr/local/lib/lua/5.1/loadall.so

Feel free to adjust the 'cpath' to your likening:

package.cpath = package.cpath .. ";./Library/Modules/?.so"
