Bummer.

We had problems with wrongly linked binaries so I added checks for the
existences and functionality of the three binaries (wget, tar, lzmadec).
Unfortunately --version seems not to be supported by all tar variants.

Karl: What do you think, let us turn of the check for tar?

Reasons is that we ship wget and lzmadec so they might not function on
a specific system, but for tar we always use the system one. So I would
expect that it is working.

The error message now adds to the top:
	TeXLive::TLUtils::setup_programs failed:
	...
hope that is enough. The actual die line will not help you since it is
somewhere far away from that.

If you want to test, edit your tlpkg/TeXLive/TLUtils.pm, 
sub setup_programs, and remove the "tar" from the list of programs to
check at the end of the function.

Best wishes
