libqt4-dev wont install

[brynjulfr]

First off, apologies if this is in the wrong forum, first time needing help on these forums.

I did a fresh install of 9.04 UNR onto my netbook. everything went well, but i cannot seem to install libqt4-dev package that I need. This package readily installed when I was using 8.10 standard ubuntu. I get an error like the following:

The following packages have unmet dependencies:
  libqt4-dev: Depends: libxext-dev (>= 4.3.0.dfsg.1-4) but it is not going to be installed

I ran into a libqt-dev problem with a similar error message when I'd added a newer X repository with different 3d video card drivers.

The dependencies for the 3D support of Qt are very strict and the newer version I was running from x-swat wasn't compatible.

I had to rollback from the later version of X following this kind of procedure...

...and then I found libqt-dev installed flawlessly and I was able to compile and run some test cases with Qt.
