An analogous way like your old configure command is

<moich2-1.0.2p1_dir>/configure CC=pgcc CXX=pgCC F77=pgf77 F90=pgf90 ...

All the "environmental" variables can be specified as part of configure
command.

PS. Advantages of putting the env. variables as part of configure
command are 1) the env variables won't corrupt your working environment,
so you can configure MPICH2 with different set of compilers in the same
shell. 2) the exact configure command and options can be retrieved by a
grep on config.status, e.g.

grep -A 5 configured config.status

or

./config.status --recheck (hits control-c as soon as it runs).
