audio/bristol needs some work

[Hans de hartog]

The package audio/bristol works but the GUI is not there.
Building from source also silently omits the x11 stuff
because it's still looking in /usr/X11R6/....
It builds the x11 stuff when I do a "ln -s /usr/local /usr/X11R6"
but then lots of other things go wrong because the plist is
not complete anymore.
Can somebody fix this please?
Regards,
Hans
