send us configure.log at petsc-maint at mcs.anl.gov and we take a look
at the problem. Its probably easier to get this working than trying
the alternatives below..

It might work [see notes below]

yeah difference in compiler verson can cause problems..  [I'm not sure
 if there are issues between these intel compiler versions]. If it
 were to work - you can copy the whole petsc tree with 'rsync -a'

If PETSc was configured with Sharedlibs, there could be issues after
the move. Rebuilding sharedlibs might work arround this problem..

make deleteshraed shared

There could also be issues with external libraries. They need to exist
on the other machine - in the exact same location as the first
one. [otherwise you will get errors at compile time.
