This isn't scalable.  Our situation here is that we require several
versions of packages like gcc available simultaneously.  Different
users will use different versions.

The current Debian /etc/alternatives approach doesn't work either.

The solution I like the best is to use the /opt directory layout.


Each is self contained.  Each developer can either mount exactly the
version she requires or establish a link to it.
