This is a worksforeme. The usual place for qmake.conf is
/usr/qt/3/mkspecs/linux-x86-g++/ Are you using Qt Embedded?

Apparently so. I don't remember installing it. What is it a dependency of?
Should I unmerge it?

*  x11-libs/qt-embedded
      Latest version available: 3.3.2-r1
      Latest version installed: 3.3.2-r1

Despite it is a bit broken, you could try `qpkg -q qt-embedded`, but I don't
think, that there is something in the tree depending on it. I may be wrong
though. 

Please paste the content of "/etc/env.d/45qt3".

As requested (/etc/env.d/45qt3)

PATH=/usr/qt/3/bin
ROOTPATH=/usr/qt/3/bin
LDPATH=/usr/qt/3/lib
QMAKESPEC=linux-g++
MANPATH=/usr/qt/3/doc/man

This loos odd:$ qpkg -nc -q qt-embedded

Should I umerge it?

Hm, your Qt Environment data seems to be correct. Does `echo $QMAKESPEC` print
linux-g++, too? If yes, then unmerging qt-embedded and emerging sip afterwards
should work fine.

Nearly. 

# echo $QMAKESPEC
qws/linux-x86-g++

O.k. Unmerge qt-embedded, do `grep -HR qws /etc/env.d/`. Delete the file that
will show up, do `export QMAKESPEC=linux-g++` and then emerge sip.

I unmerged qt-embedded. 

grep -HR qws /etc/env.d/ returned no files to be deleted. 

Emerging sip worked after your instructions. 

Thanks for that.

So, who should close this?

Please don't, Daniel.

herd, what shall we do? Should Qt's QMAKESPEC supersede QtE's, should Qt and QtE block each other, do we set QMAKESPEC in the kde-functions.eclass or do we ignore the issue just like the other Qt Embedded bugs? ;)

copying from bug 80761:

  I think the best solution is to not add
  neither QTDIR nor QMAKESPEC to the environment, to be absolutely sure that
  we don't conflict with standard Qt. Consider that nothing in the portage
  tree depends on qt-embedded, the only exceptions being 
  media-tv/{mythtv,mythbrowser}, but in newer versions qt-embedded was also 
  removed from there.
  If someone uses qt-embedded for his own project, he just have to set QTDIR
  and QMAKESPEC to the values he desires. This is explained in an einfo at the
  end of the ebuild.

qt-embedded-3.3.4 committed with the fix above.
