Bugzilla Bug 69105

The configure script that ships with amanda uses 'tar --version' to check if
the tar program is gnu-compatible.  Because of the new output of tar 1.14.90,
this check fails.

Reproducible: Always
Steps to Reproduce:
1.emerge ">app-arch/tar-1.14"
2.emerge amanda

Actual Results:  
"configure: WARNING: *** /bin/tar is not GNU tar, so it will not be used."

amanda is installed WITHOUT tar support!!  Only dump support (AFAIK, this
requires ext2 or xfs 
partitions smaller than your tape size)

Expected Results:  
amanda should install with tar support

A trivial work-around is to make sure emerge uses a previous version of tar. 
Here's the patch 
(works with all amanda ebuilds currently in portage):

The "correct" way to fix this would be to patch amanda's configure files to
handle this situation.  
It could check the version number in the new format, but should probably also
check gnu --help 
or attempt to use the needed arguments as well:  GNU-incompatible tars (such as
star) have a 
similar --version tag.

please submit a patch to fix up configure if you could...

The tar developers have fixed the output of 'tar --version' in the CVS, so
hopefully only 1.14.90 (an alpha release) will be a problem.  We can still make
a patch since 1.14.90 is in portage & will screw things up if it is the system
tar.  I will need to check the output of 'tar --help' for all the versions of
tar that are in portage & will also need to check to make sure that star
doesn't return something similar.  I can do this next weekend.

Alternatively, we can patch tar 1.14.90 since the upstream provider has fixed
the output for future versions.

Patch for amanda configure files to allow it to work with tar-1.14.90

Because GNU has promised that the output to 'tar --version' is fixed in CVS, we
can merely explicitly force amanda to work with tar-1.14.90.
