This is because dev-python/PyQt needs qscintilla to build and qscintilla's
python bindings need PyQt. I've moved dev-python/qscintilla to
x11-libs/qscintilla today and added a separate package called
qscintilla-python to the tree. This should fix this problem.
Thanks for reporting ;)

Well, now we have a nifty collision on upgrade because the order is wrong...

# emerge -uDpv world

[ebuild  N    ] dev-python/qscintilla-python-2.1  USE="qt4" 0 kB 
[ebuild     U ] x11-libs/qscintilla-2.1-r1 [2.1] USE="-debug -doc -examples python qt4" 0 kB 

Change it like this:

<snip>
--- qscintilla-python-2.1.ebuild	2007-11-20 06:04:49.000000000 +0100
+++ qscintilla-python-2.1.ebuild	2007-11-21 22:57:48.000000000 +0100
@@ -19,6 +19,7 @@

 	!qt4? ( dev-python/PyQt )"

and it works:

# emerge -uDpv world

[ebuild     U ] x11-libs/qscintilla-2.1-r1 [2.1] USE="-debug -doc -examples python qt4" 0 kB 
[ebuild  N    ] dev-python/qscintilla-python-2.1  USE="qt4" 0 kB
