You can't change the defaults (no configuration, as they're hardcoded)
but you can set the values CC and CXX passed to configure at runtime:

port build configure.cxx=pgcpp

If used a lot, a new "configure.compiler=pgi" option could be added to
the current list of presets (such as "gcc-4.0" and "macports-gcc-4.2") ?

Then again, there is no default configuration for that either...
So it would just mean having to set one variable instead of two.


PS. For us non-academics, the price tag looks a bit steep.
     But it (and the Intel compilers) could be added anyway.

port build configure.cxx=icpc
