Hi Robert: Thanks for the advice and I'll try posting to the mailing list you mentioned. For what it's worth, the option, --fcompiler=gnu95 yileds the following error in the second calling of f2py: error: don't know how to compile Fortran code on platform 'posix' with 'gnu95' compiler. Supported compilers are: compaq,absoft,intel,gnu,sun,f,vast,ibm,lahey,intelv,intele,pg,compaqv,mips,hpux,intelev,nag) Cheers, t. -- http://mail.python.org/mailman/listinfo/python-list
