	For my $0.02, I don't believe that including graphics in libpari is an 
acceptable idea.
	I have just spent an entire afternoon trying and failing to build a 
program that links against libpari (at version 2.2.8) and doesn't use 
any graphics whatsoever. No matter what loader flags I pass, it fails with:

/usr/local/lib/libpari.so: undefined reference to `plot_outfile_set'
/usr/local/lib/libpari.so: undefined reference to `set_pointsize'
/usr/local/lib/libpari.so: undefined reference to `rectdraw0'
/usr/local/lib/libpari.so: undefined reference to `term_set'
/usr/local/lib/libpari.so: undefined reference to `PARI_get_plot'
collect2: ld returned 1 exit status

If I wanted graphics, I'd write the program to call a graphics library 
on its own. Why should I have to go through some torture related to 
portplot.o? Am I condemned not to be able to link non-graphical programs 
against libpari so some hypothetical developer who wants to use graphics 
but only knows the pari overlays - get real!
