So far, I am the only person that has been successful with it.  There are
lots more reports like yours on plplot-devel.  However, because of my
success we hope to find a small tweak that will allow building the f95
interface on more than just my platform.  My platform (Ubuntu Breezy with
gfortran-4.0.1) had no g77 installed.  (g77 tends to confuse issues with
gfortran.) To emulate that, be sure to set the F77 and F95 environment
variables to be the same as FC and FCFLAGS. (Those variables are reported in
config.summary).  Also, be sure that gfortran is installed. (/usr/bin/f95
symlinks to gfortran on my system.) My experience is that the gfortran
compiler is fine for compiling both our f77 and f95 interfaces. Finally, you
might want to try the --tag=F77 option for the above libtool command to see
if that variation works by hand.

I will be most interested to hear of any tweak success/failures to follow
what happens on my platform, i.e., both the f77 and f95 interfaces are built
by gfortran with no problems.
