I would have thought that many organisations would have similar
policies.

Well, yes (I was one of those admins, although not at your university, for many years), but if they are installing machines with both Xcode 4.6 under /Applications and Xcode 4.1 or earlier under /Developer, they are installing broken machines that will fail to build many packages and where Xcode may malfunction. /Developer should not exist on a machine with Xcode 4.2 or later installed, at all. You should contact an administrator about this and have them fix both installed machines and their installation images or maintenance routines (whatever they went with for OS X).

sudo /Developer/Library/uninstall-devtools --mode=all

If they need an official reference on this, I can dig up the relevant Apple knowledge base article.

I have heard that it is sometimes inconsistent about this; sadly, just because it didn't notice the older version doesn't mean the older version won't cause breakage. (As you saw.)
