Mythtv depends on >=x11-libs/qt-3.1. It should check X use flag instead and either depend on qt or embedded-qt. Maybe there should probably be a QT virtual.
Created attachment 33204 [details, diff] mythtv-0.15.1.ebuild.patch ok this patch fixes compiling with qt/e and a few typos in the ebuild.

Unfortunately this broke mythtv on AMD64, since qt-embedded doesn't have amd64 or ~amd64 keyword yet: # emerge -pv mythtv These are the packages that I would merge, in order: Calculating dependencies \ !!! all ebuilds that could satisfy ">=x11-libs/qt-embedded-3.1" have been masked. !!! possible candidates are: - x11-libs/qt-embedded-3.3.2-r1 (masked by: missing keyword) - x11-libs/qt-embedded-3.1.2 (masked by: missing keyword) - x11-libs/qt-embedded-3.3.2 (masked by: missing keyword) !!!

This only happens if you have directfb in your USE flags. I will add ~amd64 to qt-e anyway, but this probably isn't what you want as it will emerge qt-embedded. Unless you really are running directfb mythtv on an amd64?
Okay, I'm afraid I still have problems when I have directfb in USE: # emerge -av mythtv These are the packages that I would merge, in order: Calculating dependencies ...done!

Alright, I can't test this myself, but this should work if you build for embedded x86 platform on amd64. In qt-embedded-3.3.2-r1.ebuild change the line: use x86 && myconf="$myconf -embedded x86" || myconf="$myconf -xplatform generic -embedded generic" to: use x86 && myconf="$myconf -embedded x86" || use amd64 && myconf="$myco\ nf -embedded x86" || myconf="$myconf -xplatform generic -embedded generic"
The 0.15.1-r1 ebuild in portage uses use flag X but it IUSE doesn't include X. I think thats a bug. I'm not sure I like the logic of the ebuild. Right now I seem to have X and directfb use flags set (even though I didn't set directfb myself in make.conf and its not in make.default---how can that happen?) and still this ebuild wants to install qt-e. Why should the directfb use flag "win" over the X flag? mplayer for example uses both the X and directfb use flags to enable support for both X and DirectFB. I think I agree with the originally poster: why not make mythtv depend on a KDE virtual and then decide whether its qt or qt-e at that level. Also, can someone explain how the following happens: Here is partial output of euse -i: X [+] [D] [G] Adds support for X11 directfb [-] [ ] [G] Adds support for DirectFB layer (library for FB devices) now here is the results of emerge -vp mythtv: [ebuild N ] x11-libs/qt-embedded-3.3.2-r1 -build -debug -doc +gif +mysql -odbc +opengl -postgres 19,159 kB [ebuild U ] media-tv/mythtv-0.15.1-r1 [0.15.1] +alsa +arts -cle266 +directfb -dvb -lcd +lirc -nvidia +opengl 0 kB how does the directfb use flag get set? its not set according to euse but then it is according to emerge!
Sorry should have read "QT virtual"
Added X to IUSE. Not sure about why directfb is being set, but directfb doesnt "win" against X. If you set directfb and X they should both be detected by mythtv and compiled. I'm not sure if this works, as I haven't tested it. Directfb is a layer over the framebuffer device. If you want an X version of myth, and not a framebuffer version, set USE="-directfb X". If you want a directfb version of mythtv (which is what you are saying if you have directfb in USE) then qt-embedded has to be a dependency, because it is the only version of QT that runs on a framebuffer device. I agree that the QT virtual would probably still be a good idea.
I got -r1 to compile when I removed directfb from the ebuild USE, and added X. unmerged qt-embedded. In make.conf to USE add -directfb. Then mythtv compiled. Thanks Chris.
