port reinstall does not update /var/db/pkg (libreoffice)

[O. Hartmann]

Libreoffice undergoes a lot of chenges these days, so updating the port 
from siurce takes more than four hours on my boxes. On one of the, 
running FreeBSD 9.0-CUR/amd64, portmaster fails to update to 
libreoffice-3.3.0_3, process quits with random strange errors. Doing the 
job from ports/editors/libreoffice via 'make reinstall' works fine, but 
this does not update /var/db/pkg/libreoffice-3.3.0_3 properly, so that 
everytime I perform "portmaster -av", libreoffice shows up again, 
claiming being libreoffice-3.3.0_1, wanting to be updated to 
libreoffice-3.3.0_3 (not realising that it is already 
libreoffice-3.3.0_2, because I updated sunday the last time and after 
the today's update it is de facto libreoffice-3.3.0_3, but 
/var/db/pkg/libreoffice-3.3.0_1 clains still to be libreoffice-3.3.0_1).

How to fix this?
