Thank you for responding so quickly Lenard. I've just
tried your example. I entered the following commands:
pyrexc restaurant.pyx
gcc -c restaurant.c -I/usr/local/Python-2.2.2/Include 
 -D__pymoduleinit__=initrestaurant
pyrexc dishes.pyx
gcc -c dishes.c -I/usr/local/Python-2.2.2/Include
gcc -o restaurant restaurant.o dishes.o
-L/usr/local/Python-2.2.2 -lpython2.2 -ldl -lpthread
-lutil -lm  -D__pymoduleinit__=initrestaurant

I tried it on the command line and i get the
following:

$ restaurant
Exception exceptions.NameError: 'dishes' in
'restaurant.prepare' ignored
42 oz spam, filler no. 135414616.

The 'cimport dishes' didn't work but strangely enough
'from cdishes import spamdish' did !!

I tried it again by replacing 'cimport dishes' with
'from dishes cimport sausage' and then i get the
correct result: '42 oz spam, filler no. 0.'

I am puzzled about why this doesn't work!

Thank you for helping
Alain
