One problem is that some ported software hard-codes some absolute paths.
Moving files around might break them.

Well, there's also the other problem that some software might need to be
installed twice for hybrid builds. E.g. on a gcc 2 hybrid a gcc 4 version
of OpenSSL is needed for WebPositive and a gcc 2 version for Mail, ssh,
etc. So one would also have to adjust the build system to support that case
and make sure that the packages don't clash with each other.

Good question. If the status quo appears to work and we want to do a
release soon, we might indeed want to sit this issue out until package
management is introduced (hopefully before the subsequent release).
