The Engine uses standard Linux error codes when possible.  2 is ENOENT, "No
such file or directory".  Something is missing that the Engine or one of
its plug-ins needs.  Not very descriptive.  The Engine can return ENOENT
for a variety of reasons.

Try running "evms -d everything" which will open the Engine with debug
level set to "everything".  All internal messages will go to the log,
/var/log/evmsEngine.log.  Send me the log or post it here.  I should have
some clues as to what is missing.
