The build fails with Qt because PARI does something wrong with the
include search path (Qt headers are in a subdirectory Qt, and this
isn't taken into account by PARI).

A build with X11 and with FLTK succeeds, but they are both buggy.
With X11, redraw is sometimes incorrect after resizing the window
(this isn't new: I had noticed this problem before). With FLTK,
the GUI part freezes (at least on my machine), but I don't know
who is the culprit. So, X11 seems to be preferable.

BTW, I have the following warning:

$ port lint pari
--->  Verifying Portfile for pari
Warning: Variant x11 overrides global description
--->  0 errors and 1 warnings found.

I wonder what the cause is, as this looks very similar to other
portfiles, for which there are no warnings.

OK, I agree.
