If you have installation issues - send the relavent logs [in this case
configure.log] to petsc-maint.

Here you appear to try too many things.. But its not clear if you are
installing openmpi/lam yourself - or using default from Red Hat 3.4.
[note - default openmpi will be built with gnu compilers - so
unuseable from ifort].

Thing to do:

- decide on compilers you want to use.
- build PETSc and mpi with these compilers

[for eg: configure CC=icc CXX=icpc FC=ifort --download-mpich=1 --download-hypre=1]

Note: alternative f90 compilers seable on linux are gfortran, g95
