IBM RAD 8.0 installation fails

I’m tying to install Vaadin plug-in into RAD 8.0 (Eclipse 3.6.2) on RHEL 64 bit. I get the error bellow (it’s looking for SWT source?). I tried it on the same machine with Eclipse for JEE developers V3.7 and I had no problem there. Did anybody succeed in installing Vaadin on RAD 8?

The error:
Cannot complete the install because one or more required items could not be found.
Software currently installed: Shared profile (SharedProfile_bootProfile
Missing requirement: Shared profile (SharedProfile_bootProfile requires 'org.eclipse.swt.gtk.linux.x86_64.source [3.6.3.v3659d]
’ but it could not be found

Classic, you have to start RAD as root and then it’s OK.
