And whether you do that or not, remember to compile PyQt using the -c
for concatenate (IIRC) switch -- huge reduction in compilation time.

Make sure you build them in the correct order.
Qscintilla
sip
PyQt

I had some kind of .so problem and Detlev mentioned to run ldconfig.
Problem solved. If it doesn't fix your problem, he'll probably be along
shortly.

Haven't been using it long, but eric and qt designer is pretty nice
stuff.

Well, that's what I did in the end. I compiled Qt 3.1.2 from sources and now
it works perfectly. Thanks!

I just got PyQt going on Mandrake, and it's a trick.

Best way I found was to go to http://www.rpmfind.net and grab the .src.rpm's
of PyQt and SIP, edit the .spec files to ensure that you're using the correct
Python version, and build from source (rpm -bb <specfile>).

Another way is to use the packages from pykde.sf.net, which are a bit older,
but seem to work fine.
