I am trying to do this compile as anyone would do any other software package
which would generally have an install stage that comes after the compile and 
test phases.  So the safe bet is to set CONFFLAGS with something like 
this : --with-udev-rules-dir=/opt/xorg/udev

Dis that and the compile now proceeds but there will need to be some funky 
install done later to copy those bits in /opt/xorg/udev over to the /etc dir.

Maybe .. not sure. 

Doing a compile as root is just not going to happen.  Not without a full system 
backup first.

oooops .. spoke too soon.  the compile just failed again and quickly too :

configure: error: Package requirements (mtdev) were not met:

No package 'mtdev' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables MTDEV_CFLAGS
and MTDEV_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Looks like another dependecy needed. 

When I get to the end of this process I plan to write a detailed article that shows
how you too can build X.  Except with all the dependencies laid out up front 
as well as the secret[1] tricks to make it work.
