ports creating files under /root - why?

[Anton Shterenlikht]

I noticed that some ports create directories/files
under /root:

drwxr-xr-x   3 root  wheel   512 Mar 19  2012 .subversion
drwxr-xr-x   2 root  wheel   512 Mar  4 10:23 .qt

drwxr-xr-x   2 root  wheel   512 Jul 10 15:27 .astkrc
drwxr-xr-x   2 root  wheel   512 Jul 10 15:27 flasheur
(these two are probably related to
astk-client-1.11.0             cad/astk-client
astk-serveur-1.11.0            cad/astk-serveur
fr-aster-10.8.0.3              french/aster
)

# ls -al /root/.local/share/webkit/
total 12
drwx------  3 root  wheel  512 Jan  3  2013 .
drwx------  3 root  wheel  512 Jan  3  2013 ..
drwx------  2 root  wheel  512 Jan 30 01:45 icondatabase
# 

I thought everything goes under /usr/local.
Am I wrong?

Thanks

Anton
