>Description:
$ perl -e 'use Filesys::DiskFree; my $df = new Filesys::DiskFree; $df->df();'
No df command known for format freebsd at -e line 1

When you look into ${PREFIX}/lib/perl5/vendor_perl/5.10.0/Filesys/DiskFree.pm
you'll find that many systems are just not supported.
>How-To-Repeat:
perl -e 'use Filesys::DiskFree; my $df = new Filesys::DiskFree; $df->df();'
>Fix:
Rewrite part of DiskFree.pm?
