no i have not seen this before (i usually compile espresso on linux
and have little problems with that), but please have a look at the
file pwtools/metadyn_pp.f90.
the subroutine PGOPEN is only referenced when the define
__PGPLOT is set. looks like your preprocessor did not work
correctly, or some system tool is intrinsically defining __PGPLOT.
please try to add as the first lines in pwtools/metadyn_pp.f90:

#if defined(__PGPLOT)
#undef __PGPLOT
#endif

however this kind of behaviour makes me doubt, whether the
preprocessor of this g95 distribution works properly at all.

axel.
