I struggled for ages with this just last week on Mandriva. I was missing 
a couple of important steps.

You have copied the .so file to $QTDIR/qt/plugins/designer and then 
restarted designer? Don't forget the bit about restarting designer!

You should have libwidgetnameplugin.so in the 
$QTDIR/qt/plugins/designer where widgetname is the name of your custom 
widget.

Don't forget also, that you'll have to add the new lib name path to your 
.pro file and have the header file available for your program to compile!

Oh, the other thing to be sure is that designer is built with the same 
version as creator and you're not using an incorrect version of designer 
from your respoitory.

Good luck. This is really confusing at first!
