Mostly because I was able to do a full build once before, years ago, and
I have not tried since. A perfectly reasonable exercise to build from
sources wouldn't you think?

Nothing beats the source for a worth while test. 

At the moment I am seeing many warnings and I fear that the process that
worked only a few years ago won't any longer. 


Things like : 

warning: failed to load external entity
"/opt/xorg/share/doc/xorg-docs/xext/lbxalg.html.db"
warning: failed to load external entity
"/opt/xorg/share/doc/xorg-docs/xlfd/xlfd.html.db"


also I think this may be wrong : 

xorg$ CONFFLAGS=\-\-with\-udev\-rules\-dir\=/opt/xorg/udev
xorg$ export CONFFLAGS

The idea here is to build everything into /opt/xorg but thus far I don't
know if this is correct at all anymore : 

 ./util/modular/build.sh --clone --autoresume built.modules /opt/xorg


Anyways, a perfectly reasonable thing to try.
