[OMPI users] compile openmpi with a gcc that is not default gcc??

[Shafagh Jafer]

I have a simple question:
My default gcc is 2.95.3, so I installed a newer version in my own home 
directory, it's gcc-3.4.4. Now I want to install openmpi and compile it with 
this new version. I dont know how to force it not to pick the default one. I 
want it to use the 3.4.4 version. Please let me know what to do exactly. Thanks.
