pure: add warning on version upgrade if old modules are installed

[ryandesign@…]

Pure has the feature that modules are installed into the directory ${prefix}/lib/pure-${branch} so if Pure is updated to a newer version then any existing modules you've installed aren't accessible anymore until you forcibly rebuild each module so that it gets installed into the new pure lib directory. This is ​intentional because Pure has not yet reached stability and is still changing often, such that a module compiled for a previous version of Pure probably won't work with a current version anyway.

It would be nice if pure (and pure-devel) would output a message if they are upgraded to a newer version and the user has installed modules so that they know they need to rebuild them.

Fixed in r47629.

This didn't work so well. Running the check at post-install or post-activate time just caused a hang. I had to change it to run at post-destroot time. Fixed in r47630.
