This is not the list to discuss such matters, but something is wrong 
with your toolchain.  A version of gcc which supports OpenMP should have 
a libgomp.spec file, in one of the places it looks for .spec files.

It maybe that you need to install something other than gcc to get it, 
especially on micro-packaged distributions.

But e.g. on my Fedora 16 it is file
which is part of the gcc RPM.
