I realized I didn't need to spawn sed twice, but removing the
'(package)' stuff seems better.  Thanks for giving me a reason to fix
the whitespace.

Also the string,

 GNU assembler version 2.24.0-6.fc21 20140613

Was originally reporting '2014061320140613' prior to your version.  The
new version reports '0224' like all the others.

Fwiw,
Bill.
