You need to do something like

QMAKE=/usr/qt/3/qmake qmake mythtv.pro

I forget the exact syntax, but if you look in the recent gentoo ebuilds 
it's in there and you can just rip it out and use it from the command line

I started building a new version recently and tripped over this issue 
because I have both qt3/4 installed. 

Perhaps someone could post the exact commands and add them to the Docs.  
I should think it will affect more than just Gentoo users once QT4 
becomes part of some distros
