[OMPI users] how to install openmpi with a specific gcc

[Shafagh Jafer]

Hi!
on my system the default gcc is 2.95.3. For openmpi i have installed gcc-3.4.6 
but i kept the default gcc to stay gcc-2.95.3. Now, how can I configure/install 
openmpi with gcc-3.4.6?what options should i give when configuring it so that 
it doesnt go and pick upt the dafault 2.95.3 ???
