Dear Justin Mason,
    
This is a computer-generated report for Mail-SpamAssassin-3.2.4
on perl 5.8.1, created by CPAN-Reporter-1.13. 

Thank you for uploading your work to CPAN.  However, there was a problem
testing your distribution.

If you think this report is invalid, please consult the CPAN Testers Wiki
for suggestions on how to avoid getting FAIL reports for missing library
or binary dependencies, unsupported operating systems, and so on:

PROGRAM OUTPUT
------------------------------

Output from '/Users/jj/perl/perl-5.8.1/bin/perl Makefile.PL':

What email address or URL should be used in the suspected-spam report
text for users who want more information on your filter installation?
(In particular, ISPs should change this to a local Postmaster contact)
default text: [the administrator of that system] the administrator of that system
ERROR: the required Digest::SHA1 module is not installed. at lib/Mail/SpamAssassin/Util/DependencyInfo.pm line 294.
ERROR: the required HTML::Parser (version 3.43) module is not installed. at lib/Mail/SpamAssassin/Util/DependencyInfo.pm line 294.
ERROR: the required Net::DNS (version 0.34) module is not installed. at lib/Mail/SpamAssassin/Util/DependencyInfo.pm line 294.





note the ERRORs.  however the smoke testers never bother reading that bit before hitting "yes, send this fail report". grr.

there may be some way to fix our Makefile.PL to enforce this. if we don't "exit 1" when a REQUIRED module is missing, we should be doing that at least.
