Virtualenv: crash with Python 3.3 on Arch Linux

If I install Python 3.3 from the Arch Linux AUR and then try to open a virtualenv, I get this crash:

$ virtualenv -p python3.3 /tmp/foo

Using base prefix '/usr'

  Complete output from command /tmp/foo/bin/python3.3 - setuptools pip wheel:

There's some discussion in the comments on that AUR package about different build flags related to SSL. I get the impression that the package itself needs to be fixed somehow, so this crash is not virtualenv's fault. However, it would be nice if virtualenv was aware of this potential error, and was able to print a helpful message. Something like "The SomethingSomething package is missing, probably because your version of Python was built without BlahBlahSSL. Virtualenv doens't support that."
