build without graphics (X11)

After I ported the setiathome 6.03 and astropulse 5.00 to FreeBSD I've got some requests if it would be possible to compile the clients without graphics support. This way it is possible to run the clients on headless stations without having to install X11.

There is a --disable-graphics knob in the configure scripts but currently it is broken, because (as far as I can see) the state information of the math part of the astropulse client is stored inside a graphics structure (why?). This used to work fine in the previous version of the setiathome client (5.27).

I might be able to come up with some patches myself (against SVN head). Is there any interest for this?

I figured out that the problem is specific to astropulse, setiathome does respect the --disable-graphics option (and consequently builds a slightly smaller binary :) )

I've made an update to the port (not committed yet) to make X11 optional and to update Astropulse to version 5.03 It can be fetched from [1]. It is also available as a patch to the current port version from [2]

The clients compile but if you don't select X11 with Astropulse, the Astropulse client will crash when starting up :( If anyone knows a *proper* fix (i.e. not adding graphics-only include files) for this, let me know.
