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
