Perl 5.6.0 or newer. No problems were found with threaded Perl.
AFS system libraries and header files from B<OpenAFS 1.2.x> or newer.
It is not know whether version 0.3.0 of this module works with
B<IBM/Transarc AFS> because I don't have this version available any more.
=head1 PREREQUISITES
This package does not depend on any other Perl modules.
=head1 KNOWN BUGS
This package depends on the corresponding OpenAFS libraries.
These underlying libraries still don't work properly on or with
64bit Linux systems. The problem manifests itself in statistic
values beeing zero instead of the real value.
This problem will go away once the OpenAFS libraries are fixed.
