portupgrade error

[Kovács Péter]

Hello,

When running portupgrade I face this error:
"Generating INDEX.tmp - please wait..make: illegal option -- C
usage: make [-Beiknqrstv] [-D variable] [-d flags] [-E
variable] [-f makefile]
            [-I directory] [-j max_jobs] [-m directory] [-V

********************************************************************
Before reporting this error, verify that you are running a
supported
version of FreeBSD (see http://www.FreeBSD.org/ports/) and
that you
have a complete and up-to-date ports collection.  (INDEX
builds are
not supported with partial or out-of-date ports collections
-- in
particular, if you are using cvsup, you must cvsup the
"ports-all"
collection, and have no "refuse" files.)  If that is the
case, then
report the failure to ports at FreeBSD.org together with relevant
details of your ports configuration (including FreeBSD version,
your architecture, your environment, and your /etc/make.conf
settings, especially compiler flags and WITH/WITHOUT settings).

Note: the latest pre-generated version of INDEX may be fetched
automatically with "make fetchindex".

*** Error code 1

Stop in /usr/ports.
*** Error code 1

Stop in /usr/ports."

I am running a supported version of FreeBSD: 4.8
How can I correct this?
