As these routines as written in Fortran, try f2py. It will also write the C
interface and array size checkers for you. It is available at:
http://cens.ioc.ee/projects/f2py2e/

The scipy project (http://www.scipy.org) uses f2py to generate its wrappers 
for blas and lapack. Have a look in their tree e.g: 
           scipy/Lib/linalg/flapack.pyf 
           scipy/Lib/linalg/generic_fblas1.pyf 

Best Regards
