I have build port lang/gcc and lang/gcc46 recently on another box
running the same configuration files like the boxes which fail
(/etc/make.conf and /etc/src.conf).

When removing /etc/make.conf and /etc/src.conf as requested, first thing
I realize is that perl 5.14 wants to be installed - while I use
throughout all systems perl 5.16.

Having the default /etc/make.conf with only the PERL specific adaption

PER_VERSION=5.16.2

gives a quite short journey into compiling lang/gcc with the following
error:
