Did the unpacking succeed? Does the opera.sh script have
execute permissions? Perhaps you unpacked the tgz archive with
a tool that does not preserve execute permissions? Try the
following command in /phoneme:

chmod a+x opera.sh
chmod a+x test.sh
...

do this for all scripts

Also set the execute permission for the cvm binary:
chmod a+x bin/cvm

You can try to run a console application:
bin/cvm -cp testclasses.zip Test

or

./test.sh

I hope this helps.
