Question about kde builds

[Rik Burt]

After looking through my build logs of the new version of KDE I  noticed 
something I haven't noticed before.

During 'configure' the build tries to create a file '//.kde/share' but 
there is an error saying "permission denied".  I have SUDO defined in 
/etc/mk.conf hence I build and install the port as a regular user.

This isn't a show stopper as everything seems to work fine. 

My questions are should I be building the port as root, and why does it 
need to create this file on my 'slash' partition which is very small on 
advice from INSTALL.i386?
