I would still have problems with the unpack which I can't override.



Also, [Arfrever] on IRC suggested that instead of

if tc_version_is_between 6.4.0 7 ;  then

I use

if tc_version_is_between 5.5 6 || tc_version_is_between 6.4 7 ||
tc_version_is_at_least 7.2 ; then

to better future proof the code.  The assumption here being that gnu.org
will continue using .xz instead of .bz2 going forward which seems
reasonable.
