Could that mess up the Receipt?  I doubt it, but I'm not sure.  It
would be nice if there was an option to 'absolutely install every file
in this installer'.

Uhm, OK ... that doesn't seem like it would make life easier....

To be honest, I'm having a hard time seeing how all those topics are
related to one another. Is PGPLOT having a PNG device related to which
version of gcc is used?  I doubt it has anything to do with g95 vs.
gfortran. I also doubt that 'stealing the Fink libpgplot' is what we
want (that is, we want to avoid requiring Fink, and Fink uses a lot of
internally-consistent but hard-to-isolate dependencies on dynamic
libraries).

For PGPLOT on OS X, I just built static versions of libpng and libz
from source, renamed these to libpng_iff.a and libz_iff.a, and then
built libpgplot.a with those (and then renamed that libpgplot_iff.a)
and built ifeffit with those '_iff' named libraries to avoid any
possibility of finding dynamic libraries.  Perhaps this needs to be
redone with gcc4 (and perhaps it could use aquaterm), but I'd strongly
suggest avoiding too many dynamic libraries.
