I admit that this is not the best way to check for qt...

Check your ~/.ecasoundrc ... nowadays defaults to /usr/local/share/ecasound ...

This is true. Currently qtecasound is compiled if proper qt libraries
and header files are found and --disable-qt is not specified.
--enable-qt doesn't work as expected. Normally there's no need for it.

I added a warning.

I've now made a few changes to QTDIR, with-qt-libraries,
etc now work as expected.

Well, I really want to do this, but unfortunately I just haven't had
the time. Currently most of my free time goes to developing ecawave
(= simple wave editor based on libecasound). But I'll try to work on
