[f2py] pgf90 and openmp

[Frédéric Dubois]

hello,
undefined symbol means that a function (or subroutine) is missing when 
you link with f2py.
also i did a grep of the missing routine in my pgi.../lib folder and i 
found that libpgmp contains the missing function.
Now it seems that libnuma.so or libpgnuma.so contain the new missing 
function (it means that you have to add  -lnuma
or -lpgnuma to the f2py line). What these functions are doing ? i don't 
know. Which one is the more suitable ? I don't know ...

regards
