  I've added an 'extra.args' argument to the both the stable and the
alpha versions of glmmADMB (it may take ~ 24 hours for the change to
propagate to the versions of the packages that are available from R-forge).

  It's great that you got the alpha release to work.  I'm still a little
bit hung up on the issue of getting all the appropriate versions of the
binaries compiled & included ...
