I think this was just general advice for the newbie to compiling, who might
do everything under the same userid and get themselves into a mess by mixing
environment vars (QTDIR/KDEDIR/PATH etc.), include directories and libs from
different versions. There's no reason why you can't have different versions
of QT/KDE on the same system when you know what you're doing.

Likewise. I'm replying here using KMail from KDE2.2, whilst running an old
KDE3.1 beta, and compiling the latest CVS under a different userid :-)

I basically do the same as you, but I don't bother with a global KDE setup
(for this single user machine). The FAQ isn't really clear in its
explanation, but it hasn't been updated for quite a while anyway by the look
of it :-)
What you're doing is fine, so don't worry about the FAQ ;-)

Going into a war without France is like going deer hunting without an
