Sorry, I didn't come across clearly there, it's just my way of
talking.  I'd meant that I'd dismiss the notion that order was
important, not that I had no idea. (of course, there would have been
no reason for me to reply if that was the case.=) )

As it turns out, we were both wrong, since the myth ebuild doesn't use
those flags.  However, that's an appropriate way to turn specific
flags on or off for an individual package, if the ebuild honors them.

As is posted elsewhere in this thread, Mythtv's ebuild doesn't care
about your qt USE flags.  It wants qt3 and not qt4.

However, on a Myth-only box, masking off qt4 is the least problematic
option I have found, and putting "qt3 -qt4" in your USE flags
(regardless of order) should build software on your system with qt3
options instead of qt4.
