Hi Pearu,

Here's the complete command:

$ f2py -c -m _pytesselate pytess_simple.f pytess_roundness.f
--include_paths ../../fBDSM/includes

The file pytess_roundness.f does an include of "constants.inc". 
As you can see, the constants.inc file is present in the include dir:

$ ls -l ../../fBDSM/includes/constants.inc
-rw-r--r-- 1 loose 500 294 2011-05-12 14:22
../../fBDSM/includes/constants.inc

Best regards,
Marcel Loose.
