I successfully built, as a workaround, the port x11/kdelibs4 with gcc 4.7 (port lang/gcc).

The box in question is a Dell Latitude E6510 notebook with only 4 GB of RAM, could this
be the issue? The system very often starts swapping. Even my oldstyle E8400 workstation
with only 8 GB (most recent 11.0-CURRENT) starts swapping very often and recently, I saw
musterious compiler erros and stopping compiling processes never seen bevor. Restarting
the failed portbuild most often finish successfully.
