Octave-dev on Ubuntu-11.04-64bit: failed "pkg install abc.tar.gz"

[YuHong]

May I have a question about the following issue?

I recently updated workstation to be able to install Linux distribution Ubuntu-11.04-64bit.  Then I downloaded octave dev source and has been able to build it.  However, in the resulted octave environment, I tried to install packages but failed with the error messages:

octave:2> pkg install miscellaneous-1.0.11.tar.gz

Now I am trying to compile stable octave-3.4.2 source, and will try installing packages again.  Meanwhile, much appreciated if any suggestions on the above-mentioned problem.  Thanks a lot!
