RadRails and SVN

I installed the Eclipse 3.2, Subclipse, and RDT:
http://updatesite.rubypeople.org/release and
RadRails: org.radrails.updatesite.

I am getting the “Failed to load JavaHL Library” error message when I go
to Preferences → Team →
SVN tab.

This is also happening in standalone RadRails installation. How can I
fix this? TIA.
