THANK YOU ! Actually, the key is to disable AWT before loading the R
packages.
At last, it works with just a few warnings.

The key is you have to deactivate AWT BEFORE loading RWeka/Snowball.
If I do

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. My code snippet as below:
dtm<-
textmatrix
(ldir
,minWordLength
=1,stopwords=stopwords_en,stemming=TRUE,language="english")
