I'm glad you overcame the problem; however, keep in mind that the
problem was not that the graphic subsystem was included, but that
*only half* of it was included.  Obviously, this lead to linking

I do not know any argument against such a separation...

Where is it going to find this file?  I propose a small shell script
pari_config which will emit the contents of configuration; something like

  echo <<'EOE'
  parigp_l="-LXXX -lyyy"

And put it on PATH alongside the gp executable.

Hope this helps,
