A little history - Our group used to use the hpc.sourceforge compilers in the past be we stopped doing that 'cause many things were broken with Xcode 3.2.2. At that time, we added support to libMesh to properly detect the Mac compilers which have been working well for us. However we typically build our own MPICH2 instead of using the Apple supplied wrappers because we need Fortran support. This means that I don't know what if any issues you'll have with using the Mac supplied wrappers since I have never tried them. I wouldn't expect any issues though so I don't believe that has anything to do with your current issue. If you haven't recompiled Petsc since you switched compilers that could easily be a source of this problem. I would suggest that you make sure that your HPC compilers are completely removed and that all of your various search paths have been sanitized of those paths before reconfiguring and recompiling Petsc. I expect that you'll run into issues running the Petsc examples if things don't work correctly at that stage. If that all goes well, then you should be able to clean out your libMesh installation, reconfigure and recompile it and get back up and running.
