The Sys.setenv(NOAWT=TRUE) code indeed solved my problem which was excatly what Julien described.
The key is you have to deactivate AWT BEFORE loading RWeka/Snowball. If I do so it will fire a few warning messages but that should not affect anything. I am running the lsa package which requires RWeka and Snowball. My R version is 2.14.1, under Mac OS X 10.6.8.
