>Description:
When I try to build koffice, for example, I get this message while configuring:

[..]
checking if C++ programs can be compiled... no
configure: error: Your Installation isn't able to compile simple C++ programs.
Check config.log for details - if you're using a Linux distribution you might 
miss
a package named similar to libstdc++-dev.
*** Error code 1

The config.log tells me (for example):
[..]
configure:3871: c++ --version </dev/null >&5
===>
===> Please add USE_LANGUAGES+=c++ to the package Makefile.
===>
[..]

When I add this line to the Makefile, the error message is gone. Do I have a 
misconfigured pkgsrc installation, or is this "expected behaviour"?
>How-To-Repeat:
cd misc/koffice
bmake install clean
