Alexei,
It is our intention that PETSc be easy enough for anyone to install that
rather than making your application work with different versions one simply
install the PETSc version one needs. In addition we recommend updating
applications to work with the latest release within a couple of months after
each release.
If you ever have trouble with installs please send configure.log and
make.log to petsc-maint at mcs.anl.gov
