make world /jail -> error

[Martin Zibert]

Greetings..

I have a box running FreeBSD 5.3-RELEASE-p5 - today i was trying to
set up a jail, but i got this error:

.. if i'm not mistaken, make.conf should have something to do with it.
My make.conf looks like this:

# -- use.perl generated deltas -- #
# Created: Mon Feb 14 16:29:10 2005
# Setting to use base perl from ports:
PERL_VER=5.8.5
PERL_VERSION=5.8.5
PERL_ARCH=mach
NOPERL=yo
NO_PERL=yo
NO_PERL_WRAPPER=yo
NO_KERBEROS=   true
CFLAGS= -O -pipe
NOPROFILE=     true

I really don't see the problem - i've googled the net and i few people
have the same problem - non of them resolved it. Any suggestions?
Thanks in advance.
