open mp problem when installing R

Dear R People: I'm back to installing R from source, this time on a 64 bit machine.
What OS?
I'm using the R-Patched.tar.gz as my source. When I have the openmp option set to -fopenmp, I get the error that libgomp.spec is not found. Ok, so I commented out the reference to openmp. However, I ran an openmp "hello world" program using gcc and the -fopenmp option, and it ran fine.
What am I missing, please?
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 /usr/lib/gcc/x86_64-redhat-linux/4.6.3/libgomp.spec which is part of the gcc RPM.
Thanks, Erin
