Make sure the Makefile and distinfo file (/usr/ports/lang/gcc46/distinfo)
are up to date.  If you are absolutely sure you want to override this
check, type "make NO_CHECKSUM=yes [other args]".

The mirror you are using per your e-mail --
ftp://ftp-stud.fht-esslingen.de/pub/Mirrors/sources.redhat.com/
-- provides a broken image.

I have done several downloads myself, from the original source
and other mirrors, and always get the correct checksum (and a
matching tarball), that is, the one matching gcc46/distinfo in
FreeBSD Ports CVS.

If you download directly from 
ftp://gcc.gnu.org/pub/gcc/snapshots/4.6-20120608/gcc-4.6-20120608.tar.bz2
and put that into ports/distfiles, that should work?  Alternatively,
download repeatedly until it hits a different mirror?
