gcc itself does not use OpenMP.  libgomp is not not used by gcc when
gcc is itself running.  libgomp is used by the program compiled with
-fopenmp.  You do need to use -fopenmp when you are linking your
program, as well as when you are compiling it.  If you are doing that,
I think you need to tell us precisely what you are doing and what
happens when you do it (i.e., cut and paste from your terminal).
