No, absolutely not. This is my /etc/make.conf:

# -- use.perl generated deltas -- #
# Created: Wed Nov 10 22:37:45 2004
# 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

Isn't it supposed to work out of the box ? I had
no such problems with 5.1 and 5.2. Since 5.3 is
a production release, I'm quite surprised by such
problems with kernel recompilation, unless I screwed
something up.

How can I do recvsup ? Sorry for the stupid question,
I'm still a beginner.
