Judy,

Forgive me but I was away for a few days.  If you are using any version 
of Ubuntu prior to the beta release of 9.04 you will have 4.4 in the 
repos.  I should have told you that I did it on a 9.04 install ... sorry.

Now as you your questions of mixed versions you should have to worry 
because the 4.4 version you installed from the repos will be a system 
install and in different directories from any install you tried to 
compile yourself.  That is ofcourse if you didn't tell Qt to place the 
libs into the /usr/lib folder.

Cheers,

JD
