x11/kde4-workspace 4.7.4: fails to be built on FreeBSD 10

Since a couple of days I try to update/compile x11/kd4-workspace (from
4.7.3 -> 4.7.4), but it fails. Compilation fails with gcc 4.2.1 and
CLANG as well.

On FreeBSD 9.0-STABLE/amd64 boxes I tried the port can be build with
CLANG without any problem.

Waht's going wrong on my box? Any hints?

Thanks in advance,

Oliver
