Many thanks for all the feedback - as the originator of this thread, the
solution was to ensure that the PATH was defined with qt3 first so that
the correct qmake was found. Looks like its dbus that has pulled in qt4
(trying to get the Skype API to do something useful!!), just trying get
rid of it now :-)
Having built SVN mythtv manually every couple of weeks for the last year
or so, perhaps now would be a good time to find a generic ebuild that
updates an "in progress" svn local copy and then compiles it (or can an
ebuild only download from scratch?).
So if anyone has such an ebuild lurking, I'd be very interested in a looksee.
