I can't guarantee that W'13 will build (try it!), but I have built S'13
with RHEL6+Anaconda 1.8.0.

For RHEL6, you'll want ensure Anaconda Python is in your path, then
follow the build-from-source instructions until just *before*:

	eups distrib install --nolocks -t Summer2013 lsst_distrib

and *before* you run that command, do:

	cd $LSST_HOME
	cat >> site/manifest.remap
	        python  system
	        numpy   system
	        scipy   system
	        matplotlib system

That should make the stack use the system python, instead trying to
build its own.

Let us know if it worked.

PS: I just typed this above, so watch out for typos!
