Cleaning up after installing packages

I've got a 9GB /root with a little over 6GB used. I've not installed
*that* much at this point other than the gnome and kde meta-packages.
However, I ran 'make' only in these directories (no 'make-install'
needed???) but never a cleaning option.

Perhaps this could account for the large amount of disk spaced being
used. If so, what's the 'best' method to go back and clean to free up
more disk space?

Thanks!
