Now I expect that your gcc 4.3.0 does not do the right thing. You should have installed Apple's version of GCC in /usr/bin that comes with the XCode tools. Now, how can you do that?

Thomas,

Your suggestion to remove /usr/local/bin out of my system's $PATH 
environment variable and then do the installation worked, "Thanks a lot, 
we're breathing again!"

One  final question though; do you have any thoughts as to why gcc 4.3.0 
from hpc.sourceforge.net is different from what Apple supplies with XCode?

 Again, thank you for your help.

Sam Dupree.
