Probably overkill, but 50+ times I'd guess, each time as I re-arranged the order of \
the listing in /etc/ld.so.conf, which currently looks like this:

/usr/kerberos/lib
/usr/X11R6/lib
/usr/local/kde/lib
/usr/lib
/usr/lib/qt-2.3.1/lib
/usr/lib/qt-1.45/lib
/usr/lib/qt2/lib
/usr/local/lib
/usr/local/lib/sane
/usr/lib/qt-3.0.4/lib

Those libraries are, according to locate:
[root@coyote root]# ls -l `locate libqt-mt.so`

And I just rm'd the usual suspects in the mosfet-liquid src dir, reset QTDIR to the \
Aug 8th versions and reran ./configure, getting this:
checking for Qt... configure: error: Qt (>= Qt 3.0.2) (library qt-mt) not found. \
Please check your installation! For more details about this problem, look at the end \
of config.log. Make sure that you have compiled Qt with thread support!

Now, from config.log, line 9454:

This report goes on for another 1000 or more lines
each one naming a different include.

It appears the real problem might be the includes, as in a
qt2 or older (1.45) version lives at /usr/local/qt/include

But, I just mv'd that /usr/local/qt dir to qt-orig, and made a link from qt to
/usr/lib/qt-3.0.4 and it fails for not finding anything qt related then.

Then i did a locate on 4/include/q and linked /usr/local/qt to that.
That was /usr/src/garnome-0.12.2/kde/qt-copy/work/qt-copy-3.0.4
apparently the only place valid includes lives for qt-3.0.4!  In 
other words, it fsking worked!  ./configure actually ran.

Now I'm seeing if it will make.

Nope, half a kajillion undefined references at collect2 time.
But I didn't set $QTDIR to that .
Didn't help...

I'm going out for a haircut and a monitor for my old vintage coco3.
Maybe someplace in all this blather, is a clue, he said pleadingly.
