Are you sure it is possible at all to use the thread-safe API in a Perl threads
environment? Some years ago it was not:
  https://lists.oetiker.ch/pipermail/rrd-developers/2005-November/001635.html
From what I see I doubt the threadsafe-functions were included by now:
  https://github.com/oetiker/rrdtool-1.x/blob/master/bindings/perl-shared/RRDs.xs#L168

Please understand that adding this feature is would be upstream work for Tobi et al.
and is beyond the scope of a packaging project. But as I may be mistaken you could
ask on the rrdtool developts mailing list:
  http://oss.oetiker.ch/rrdtool/support.en.html

It would be nice if you would drop me a note about your findings.
If you have further suggestions on enhancing the packaging or adding compile
flags just let me know.


Best regards
