Aus UPDATING:

lang/perl5.10 is out. If you want to switch to it from, for example
lang/perl5.8, that is:

Portupgrade users:
0) Fix pkgdb.db (for safety):
pkgdb -Ff

1) Reinstall perl with new 5.10:
portupgrade -o lang/perl5.10 -f perl-5.8.\*

2) Reinstall everything that depends on Perl:
portupgrade -fr perl

Na endlich hat die CPU mal wieder was zu tun
