Notice will be up until above verified and no other troubles found from recent modifications.
Removing a package or a port
The pkg_delete command can be used to uninstall either a package or a port from within Ports Jail. If you include the -x switch, you don't have to give the full name and version of the software. Be sure to give enough of a name that you don't inadvertently uninstall other software matching the name:
# pkg_delete -x kopete
If the software has other applications that depend upon it, pkg_delete will refuse to uninstall it. If you wish to override this setting, use the -xf switch to force the delete.
