You are using Solaris (or another traditional Unix) that does not provide a sane
tar, capable of dealing with the output of GNU tar. Please either set the
PERL_LL_TAR environment variable to the location of a version of tar that
understands the @LongLink convention or put a binary named gtar somewhere on
your PATH.

WHOA THERE! It looks like you've got some fancy dashes in your commandline!
These are *not* the traditional -- dashes that software recognizes. You
probably got these by copy-pasting from the perldoc for this module as
rendered by a UTF8-capable formatter. This most typically happens on an OS X
terminal, but can happen elsewhere too. Please try again after replacing the
dashes with normal minus signs.
