Help on imap/kmail on upgrade to freebsd 6.0 - more details

[digitalphoto]

Hallo,

The imap connection was reestabilished after I changed from TLS to SSL in the 
Security preferencs tab of kmail. I don't know why, maybe someone has a hint 
on how I can use TLS again.
Also, I tried to upgrade kolab the usual way (./obmtool kolab). There's an 
error like this for every package:

[: /kolab/RPM/PKG/perl-openpkg-5.8.7-2.4.0.package: unexpected operator
obmtool:WARNING: install failure. 
Missing /kolab/RPM/PKG/perl-openpkg-5.8.7-2.4.0.package openpkg is not 
installed-freebsd5.4-kolab.rpm

How can I "teach" the system that I am not running freebsd5.4 any longer? (I 
mean, how to change 5.4 to 6.0?)

TIA,
Joe Karma
