The "right" way is to use build.sh.  The -x flag says build X.  The 
default is not to build X.  The -X flag specifies where the xsrc 
directory is, if it's not /usr/xsrc.  E.g.,

	build.sh -x release

will (when run as root) build a release into the canonical places, from 
sources rooted in the current directory and X sources in /usr/xsrc.  
Add other build.sh flags as appropriate for your situation.
