Excellent, I'll prepare a repo with those packages during the day.

Ah, then you were lucky :)

Yeah, it's a bit unfortunate that we have to work with chroot, which
requires root access.  I always configure a timeout for sudo so I
don't have to enter my password on *every* invocation.  For larger
builds, like all of [haskell] for instance, I actually configure sudo
to not require a password.  Those are the only ways I know of avoiding
typing the password several times.

I invented the term Object-Oriented, and I can tell you I did not have
C++ in mind.
