in reply to Compiled modules compatible across Perl versions

You may get lucky ... but the odds are stacked so overwhelmingly against you that you should always perform a full perl Makefile.PL ; make install cycle for each module on every combination of platform i.e. OS c/w platform & perl version.

By that means, you will have run the unit tests against module on the OS version/perl version and if the installation was successful (unless you forced the install), already have removed one of the variables if you hit problems later...

A user level that continues to overstate my experience :-))
