it was x11-libs/qt-4.3.0_rc1 ...
just a guess, but using pch and distcc are probably incompatible.

looks like this might have changed in 4.3.0. I've modified the ebuild to explicitly disable pch. do a re-sync in about an hour and try it again.

Now it did compile with the distcc (on the contrary to 2 hours in about 20 minutes :-)) What about to enable the pch use flag for the average gentoo user as default and include some more voodoo like: && has distcc ${FEATURES} && myconf="${myconf} -no-pch" && einfo "pch has been disabled, precompiled headers and distcc are incompatible."
yep,we definitely need a check. moreso though, I would think for other packages that support pre compiled headers that they probably won't work with distcc either. have you had any other success/failures?

I can confirm that is qt-4.3.1-r1 and qt-4.3.2 are both cannot be compiled with pch USE flag set when distcc feature enabled. Tested in amd64 and x86 gentoo versions. May be it is good idea to disable pch flag or distcc feature when both enabled?
Same with x11-libs/qt4.3.4-r1
4.3 is no longer in portage. Feel free to reopen if the problem reappears with qt >=4.4.2
