Removing Subclipse from Eclipse

I got the following error while installing subclipse 1.6 after trying 1.8 (which failed to sync my projects):

Your original request has been modified.

Here are the steps I took to uninstall subclipse:

Eclipse > Help > Install New Software > Available Software Sites ...

select subclipse and click "Remove"

Open Terminal; list and delete all subvesion jar files

$ cd /Applications/ide/eclipse/plugins [specific to your system]

$ ls | grep org.tigris.subversion | xargs rm

Even that did not allow full uninstallation and i decided to re-install Eclipse.
