Builds fine and rpmlint is silent.

The license tag seems incorrect; AssertOS.pm and CheckOS.pm both explicitly say either GPLv2 or Artistic.

Why is the test suite disabled?  If there's a reason you can't run it, you should at least comment on it in the spec.

You're right. The licence should be GPLv2 or Artistic.

I've commented tests in previous changelog. In the second release are removed only two wrong tests. One isn't written and second try to check installed package.

Indeed, the license is good now and the tests pass:

  skipped: Test::Pod 1.00 required for testing POD
  All tests successful.
  Files=11, Tests=29,  2 wallclock secs ( 0.03 usr  0.01 sys +  0.27 cusr  0.05 
   csys =  0.36 CPU)
I don't think there's much point in running the skipped test; if you did want to run it, you'd just need a build depencency on perl(Test::Pod).

Anyway, everything looks good to me.  APPROVED
