Buildout does in version 1.5.2. That is not the version Plone 4.1.4 (see

If and when we have a reliable way to do this with standard Plone versions,
let's do it. I'd strongly welcome a PLIP to upgrade Plone's buildout
version, but until that's commonplace, we need this type of isolation.

The PIL install approach is related, by the way. Since Plone doesn't depend
on PIL, we'd need it to be managed by buildout. Right now it's commonly
installed 'globally' so what's what plone-devstart does.
