Well, there WERE major changes from
2.x -> 3.x ... if you're lucky it's just the
configure script, though.
The thing to do would be to edit ./configure
in the programs source directory and
find the version string ... check whether
you can modify the criteria to match your
version.... of course, this doesn't necessarily
mean it will compile properly ... if the prototypes
of the functions differ it might fall over.
In that case you'll need to find a version
that's been built with Qt 3.x in mind.
