	Did you install both the development package and the main qt for
3.0.3?  Or just the main package?  I don't know how Red Hat handles this
with RPMs, but here are two things you could try.

1)	From the command line, run 

ldconfig

This tells your system basically to check its libraries and see if
you've installed any new ones it wasn't aware of.  If you're building
from source and have just installed a library you needed (like your new
qt), running ldconfig and clearing out the old config.cache can often
fix the problem.   

2)	Check your symlink for qt.  Doing an ls -al in /usr/lib (on my
Slack system) I see:

lrwxrwxrwx    1 root     root            8 Jun 18 16:45 qt -> qt-3.0.3/
drwxr-xr-x    9 root     root         4096 Jun 18  2001 qt-2.3.1/
drwxr-xr-x   12 root     root         4096 Mar 27 16:49 qt-3.0.3/
 
	You may just have to delete the symlink and recreate it pointing
at the right qt.  (I'd think rpm would do this for you, but I'm not
super-knowledgeable about rpm.)

	Hope one of those helps.

Cheers,
Raven
