That's not an error message - looks like everything installed correctly 
to me. It's merely warning you that you didn't check the signature on 
the package before you installed, so it could have been tampered with.

In Fedora 14, the default SELinux settings were changed. Now executable 
stack is disabled by default (in previous Fedora releases it was 
enabled). The Intel C libraries that Modeller uses request executable 
stack, and so are being denied by SELinux.

Fortunately Modeller doesn't actually need executable stack, so you can 
simply "fix" the Intel C library. Run, as root:

execstack -c /usr/lib/modeller9v8/lib/x86_64-intel8/libintlc.so.5
