If it relates to use or development of SpamAssassin then it is on topic.

Is Qmailtoaster related to SpamAssassin?

The typical way to check that a module is found and loaded by perl is to test it specifically. Run a script that can't have an error (for example "0") and then instruct perl to load the module (such as -MNet::DNS). If it is silent then it worked. If not then it failed.

  $ perl -Mnon-existent-module -e 0
  Can't locate non.pm in @INC (@INC contains: ...trimmed...   BEGIN failed--compilation aborted.

Using that test, the following should work if things are installed correctly. Or you will get a command line message that you can use to chase down the problem further.

  $ perl -MNet::DNS::RR::PTR -e 0

This succeeded silently for me on my system and I assume should work for you as well. But with the errors you have reported I assume that it will report an error on your system but will lead you to the problem.
