KDevelop 2.1.3 breaks during compilation on the ctagsdialog_impl.moc.cpp The error seems to be a parse error in the ctagsdialog_impl.h at line 23
I get the same error.

I fixed this problem by disabling (commenting out) MAKEOPTS="-j2" in /etc/make.globals It appears that there's a dependency problem in the kdevelop makefile somewhere. If you're running on a dual processor system, make is running 2 jobs concurrently, and the job that is supposed to create the ctagsdialog_impl.h file is apparently running behind. If you emerge again without the -j2, make will run single process and it seems to build just fine. BTW, this is not a problem with the ebuild. The same problem happens if you pull the source direct from KDE, and build with a "make -j2". A simple build with just "make" will compile kdevelop without a problem.
If that fixes it it's a duplicate of 6199. We now enforce make -j1 in the kdevelop ebuild. *** This bug has been marked as a duplicate of 6199 ***
