Hmm - sometimes sun compilers require the static libm - so the
following additional option might
work. '--LIBS=/usr/lib64/libm.a'. Otherwise - send us configure.log at
petsc-maint at mcs.anl.gov

Another note: we always recommend debug build of PETSc for
development. One should worry about optimized/performance builds -
only after developmenet is done and when performance numbers are
captured [perhaps for publishing].
