freebsd stable - Feb 2008 - CC messed up in RELENG_7 build

The sources were csupped ~3 hours ago. My CC is defined as follows:
env CCACHE_PREFIX=/usr/local/bin/distcc /usr/local/bin/ccache cc

I have done many buildworld, buildkernel and port builds with this setting and
it never caused any problems. However today buildworld fails the following way:

env CCACHE_PREFIX=/usr/local/bin/distcc /usr/local/bin/ccache env

It looks to me like there has been some kind of recursive substitution of CC,
turning
env CCACHE_PREFIX=/usr/local/bin/distcc /usr/local/bin/ccache cc
into
env CCACHE_PREFIX=/usr/local/bin/distcc /usr/local/bin/ccache env
CCACHE_PREFIX=/usr/local/bin/distcc /usr/local/bin/ccache cc

I have looked at the involved Makefile.in files, but I didn't find anything
that
looked suspicious to me.

I have found the problem, it's specific to sysutils/bsdadminscripts.
So nobody needs to spend time on it, apart from me, that is.
