Re: [f2py] Compiling/linking the Fortran source files manually

The version match text is "EM64T-based|Intel\\(R\\) 64", and my
compiler gives "Intel(R) Visual Fortran Intel(R) 64 Compiler
Professional for applications running on Intel(R) 64, Version 11.1
Build 20100806 Package ID: w_cprof_p_11.1.067". So it should actually
match both intelem and intelvem.
