Same error without distcc. Changing MAKEOPTS to "-j1" allows the merge. Possibly push to upstream?
You might want to make them aware at qt-bugs@trolltech.com, but they're working more on the 4.2.x series now and it may be fixed there already.

Call stack: ebuild.sh, line 1568: Called dyn_compile ebuild.sh, line 937: Called src_compile qt-4.2.1.ebuild, line 199: Called die Also, I've reported this up to qt-bugs at trolltech and I think it's being worked as Issue N138250.
> MAKEOPTS="-j5 -l3" Replying to myself... I'm not sure -l is supported by Gentoo in MAKEOPTS; and in any case, dropping the -l option (but leaving -j5) allows a successful build of qt. I'm going to resolve as invalid, but please reopen if MAKEOPTS containing a -l option is supported by Gentoo. Sorry for the noise. *shamed*
