Error upgrading KDE with portupgrade

[edward]

Hi all,
I have recently upgraded from FreeBSD 5.3-RELEASE to 5.4-STABLE using 
cvsup. I then upgraded installed ports using portupgrade -a (after 
running make fetchindex and pkgdb -F).
Worked for most ports.
But I have a hard time upgrading KDE from 3.3 to 3.4. Some ports in the 
KDE set upgraded OK, but kdebase among others didn't want to upgrade 
from 3.3.0_4 to 3.4.2_2. Tried :
#portupgrade kdebase
then
#portupgrade -p kdebase
The package itself donloads OK but I get the following at the end of the 
job :

Good - your configure finished. Start make now

Any clue what's going on ?
Thanks for your help.
