Comment (by mww at macports.org):

 You can add optimization flags already, e.g.
 {{{
 port -d configure libgnugetopt configure.cflags="-O3 -march=nocona -ftree-
 vectorize"
 }}}
 to overwrite the standard ''-O2'' optimization. Of course this can screw
 up the resulting binaries in fantastic ways...

 Most ports honor a subset of ''configure.cflags'', ''configure.cxxflags'',
 ''configure.objcflags'', ''configure.fflags'', ''configure.f90flags'' and
 ''configure.fcflags'' -- if applicable.

 If someone wants to make those options accessible via the config files:
 Have a look at ''portconfigure.tcl''; it should be fairly easy;
