building X11

I am trying to get on board OpenBSD via the Sharp Zaurus C3000.  I have 
cvsupped the X11 and XF4 distros, and I copied the XF4 one to the 
zaurus.  I tried to build it, was not successful, and was left with some 
quesions:

1) this is the fist time I have encountered "lndir", and I found about 
it in the XF4/README file, where it game me hints to name the XF4 as 
/source/XF4, and use lndir to create /obj/XF4 (which went ok).  The 
question occurs in trying to figure out what dir to be in for the make, 
either /source/XF4 or /obj/XF4.  It seems like a silly question, but 
seriously, I don't know trhe answer to this one, and seeing as it's not 
building for me in either place, I guess I need to know the answer.

2) the Makefile seems to be missing a "xmakefile", where does this show up?

3) if I want to build as much as possible, is the target to hit "World"?

Thanks!
