Did you show the entire output before? The reason I ask is that
it does not seem to be quite the current output, yet getting the
current version should be the first thing it does.

What is the output of: ls -l ~/abin/.tmp.install ?

If there is a .tgz file there, does it seem incomplete? I am not
sure why else the tar command would fail. What is the output
from: "which tar" and "tar --version"?
