I also tried

cd ~/lib/sablevm/classpath
mv gnu gnu-old
mv java java-old
cp -R ~/path-to-sootOutput/gnu .
cp -R ~/path-to-sootOutput/java .

and still fails, which indicates that it isn't a problem related to 
native code calling methods in untransformed classes and not finding 
them (I thought for a minute the answer to my second question was also 
the answer to my first question).

Is there some reason why inserting an empty method call (which actually 
gets recognized and transformed by me) before and after every method 
call would make SableVM fail if the transformation was applied to all of 
classpath?

Anyway, in the meantime, I'll look into the details of why I "cannot 
create vm" with gdb.
