I think that's part of the problem. What's the right(tm) way to install
qmake from qt3 and qt4? And I mean distribution packages not a separate
hand compiled tree. Like with any other library and tools I expect
headers in /usr/include libraries in /usr/lib and programs in /usr/bin.
Debian does just that. To avoid conflicts the programs get the suffix
"-qt3" or "-qt4". The original name is a link to one of the two version.
(btw, multiple versions of gcc or automake work like this too).

I get the impression, that qmake should be used ot figure out where the
rest of Qt is, right? Is there a way to ask for the right moc? I could
use `qmake -query QT_INSTALL_BINS`/uic but that's not necessarily
correct. After all qmake can be configured to use a different uic.
"qmake -query QT_UIC" or something like that would be nice.

Then the best way would be:
- look for "qmake"
- if not available or too old look for "qmake-qt4"
- ask qmake for everything else.
