Yes, I've spoken about this with cegger, but we where not able to find
what was missing, and end up doing the same workaround as you did. Will
have to look at this closely.

I guess you have the X11 sets installed? I don't have any system with
X11 installed, and never hit this error yet. Could you try to rerun
configure with:

PYTHON=/usr/pkg/bin/python2.7 APPEND_INCLUDES="/usr/pkg/include
/usr/X11R7/include" APPEND_LIB=/usr/pkg/lib ./configure --prefix=/usr/xen42

Don't know if you will also have to set APPEND_LIB to something like:

APPEND_LIB="/usr/pkg/lib /usr/X11R7/lib"
