No space left on device

["niklasro.appspot.com" <niklasro@xxxxxxxxx>]

Dear experts, one installation reports there is no space left on
device. I removed /usr/src and pkgsrc to to effect per viewed df -h.
Kindly inform what advice you can in this situation. I can always
reinstall naturally preferring something like a disk cleaup command or
script. (http://www.dragonflybsd.org/docs/user/dellcpx/)
