OK, I've tried this again, on a 6.0 stock system, starting from that 
wiki page.

Everything looked good until the 'build tools' phase:

hackbook:riz  ~/xen-4.2.0> gmake tools

<lots of build output elided>

I got past this by setting LD_LIBRARY_PATH=/usr/pkg/lib (I shouldn't 
have to; some rpath must be missing).

It built farther next time, getting into qemu:

Clearly, the include path isn't set right. (X11/Xlib.h is in 
/usr/X11R7/include)  I don't grok gmake enough to know the right place 
to set it.

Thoughts?  How was your environment set up that you didn't hit these issues?
