Fedora 10?

If you install libgomp manually (not pulled in by yum), try to uninstall it. Don't forget to check the version you have installed too.

The first rule in Linux:
Always use the package manager to install software. Do not download any rpm/deb and install manually.

If you install the *.rpm file by command rpm, you can uninstall in this way:
rpm -e libgomp

# As I have stated in other post, I don't think you need gcc. Please double check before you proceed.

1 questions:
How many RPMs you have installed without using yum?

1 suggestion:
Never compile software from the source, unless you absolutely need it.
(compile = ./configure, make, make install)
