I haven't taken the time to look into this further yet, but I can
confirm that none of the verions from 2013Q2 is building on HP-UX.

Unfortunately I spoke to soon on this.  Python's build has the annoying
habit of a successful exit status even when may of the critical modules
didn't compile.  None of this is pkgsrc's problem as far as I can tell.

That was likely just me mis-remembering what I'd done before.  What I do
see now is that hardly any X libraries will build on HP-UX because of
indirect dependency on python.  The most direct one looks to be libxcb,
which cascades into loads of further failures.

I'd certainly like python to work better on HP-UX, so will attempt to
help it out with some patches.  That'll likely take some to work out...
I'm wondering if, in the meantime, there might be ways for pkgsrc to
have fewer dependencies on python.  Anyone have pointers for this?
