Following up on #291 with version number increased, and updated %changelog.

According to this thread on CentOS 6 forums:

https://www.centos.org/modules/newbb/viewtopic.php?forum=56&topic_id=38446

installing mon from repoforge repo fails:

Error: Package: mon-1.2.0-2.el6.rf.x86_64 (rpmforge)
           Requires: perl(Math::TrulyRandom)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Looks like perl-Math-TrulyRandom package was never built correctly due to SPEC file issue. Buildlog shows errors: http://pkgs.repoforge.org/perl-Math-TrulyRandom/_buildlogs/perl-Math-TrulyRandom-1.0-1.2.el6.rf.x86_64.ko.log.gz .
I corrected the SPEC file, so now perl-Math-TrulyRandom builds fine on both CentOS 6 x86_64 and i686.
