OK, I'm getting closer :)  I threw in an ugly hack and got TQt3:

    ## hack acinclude.m4
    sed -i '/qt_bindirs=""/s|""|/opt/tqt3/bin"|' admin/acinclude.m4.in
    sed -i 's|/usr/include/tqt|/opt/trinity/include/tqt|g' admin/acinclude.m4.in

Now I can chase the unintended consequence of the aggressive use of sed and work
my way back to a clean build. Thanks for your help, I'll report back with results.
