 I'd agree with that, the question would be more when its initialisation
 should happen - I'd suggest not until it is really used, and simply
 mentioning it in the compilation unit (which is more or less all the
 program run by configure does, I think) shouldn't be enough - after all,
 a program might have an option whether it shoudl use a gui interface or not
 (several do) - we wouldn't want the program attempting to make a
 connection to an X server merely because it had been compiled to include
 a gui, when it was run with an option that causes the gui not to be used.

 My environment is fine - that's the point really, DISPLAY is actually a
 valid value (when it is bogus, the package builds).   The problem is that
 in the pkg_comp sandbox, there's no way the application can access the
 files needed to obtain correct authorisation - that's (part of) the whole
 point of using a sandbox.  So while I still believe there's some python,
 or pygtk, or similar problem here, it would also be reasonable to argue
 that there;s a pkg_comp bug as well, in that it should probably be unsetting
 DISPLAY before it starts any build, as (unless the X server is doing
 host based auth, which is even worse than its other methods) there's not
 going to be any way for the DISPLAY setting from outside pkg_comp to be
 useful inside.   I'll fix my pkg_comp to do that.
 This PR can probably close, however the problem is eventually resolved,
 it doesn't appear as if there's anything that dia-python could reasonbly
 do differently (except perhaps not bothering to do the autoconf test for
