What is the exact f2py command you are executing?
The message above means that f2py could not find the constants.inc file
within given include paths. The syntax for --include_paths reads:

   --include_paths <path1>:<path2>:...

Indeed, f2py by itself does not use -I. The -I options are used
when compiling C and Fortran codes.
