Unfortunately, it's not so easy. There are lots of paths built into
various binaries and libraries in Xorg that are derived from --prefix.
Personally, I think it would be easier if you just left it in
.../tmp/modular and directed the system to use that Xorg. Running the
modular build is discussed at the end of the wiki page:

http://xorg.freedesktop.org/wiki/ModularDevelopersGuide

Basically, LD_LIBRARY_PATH + startx the path to Xorg. You might even
be able to get it to integrate nicely with your current system by
replacing the /usr/bin/X symlink to point to your new Xorg and adding
.../tmp/modular/lib to /etc/ld.so.conf (on Linux). Overwriting the
files in /usr will probably not work unless you also built with
--prefix=/usr.
