[petsc-users] Problem with PETSc-3.2 configuration

[Satish Balay]

Glad its working now.

Wrt newer compilers - usually sysadmins [for clusters] install
separate copies of newer compilers [and leave the default system
compiler untouched]. They also install another copy of MPI with this
new set of compilers.

This workarround is ok for getting going with PETSc - but gfortran
[prior to 4.3] has some f90 deficiencies - so some of the petsc f90
interface doesn't work because of this. So its good to use newer set
of compilers. [However if using PETSc only from c/c++ - you can ignore
this issue]
