I'm afraid not.  I've been using Ubuntu 10.04 LTS as a benchmark for ensuring 
that Rosegarden doesn't require anything too new or bleeding edge.  I actually 
have to keep a separate copy of Qt 4.7 around to manage our translations, due 
to bugs in Qt.  As such, I'm pretty much satisfied if Rosegarden builds 
against Qt 4.6, and I'm not at all interested in supporting anything older 
than that at this point.

The good news is that while it's mildly inconvenient, you should be able to do 
the same thing I do to get a copy of Qt 4.7 up and going.  Unless things have 
changed since the last time I set this up, you can download a pre-compiled 
binary version of Qt from Nokia, drop it in userland, and compile Rosegarden 
against that.  That saves hours and hours of compiling Qt from source, and 
keeps the newer version separate from the rest of the stuff installed on your 
system.  It's a bit of a pain, but it's less painful than the alternatives.

I had this working perfectly there for awhile, but at some point I screwed 
something up, and now Rosegarden will compile against 4.7, but fails to link.  
I never did sort that out, I'm afraid to say.  Still, I had it all working 
once, and I'm sure the problem can be solved for less effort than upgrading 
your entire system.

Or you could just upgrade.  Karmic is obsolete, and no longer supported by 
Ubuntu.  You could probably upgrade it to LTS relatively easily, being the 
next step in line, and then you could build Rosegarden from there without any 
further ado.
