How can I fix Net::Amazon::MechanicalTurk's failing tests?

Question

I'm using Perl 5.10.0 on Debian Linux (testing) and trying to install the Perl module Net::Amazon::MechanicalTurk version 1.01. When I run the module's test suite, I get errors such as the following:

t/01-ListOperations.......................Can't locate object method "new" via package "Net::Amazon::MechanicalTurk::Transport::RESTTransport" at /home/user/.cpan/build/Net-Amazon-MechanicalTurk-1.01-BO885C/blib/lib/Net/Amazon/MechanicalTurk/Transport.pm line 21. 
dubious 
[...] 
Failed 21/33 test scripts. 12/78 subtests failed. 
Files=33, Tests=78, 46 wallclock secs ( 1.50 cusr +  0.22 csys =  1.72 CPU) 
Failed 21/33 test programs. 12/78 subtests failed. 

Net::Amazon::MechanicalTurk::Transport::RESTTransport ISA Net::Amazon::MechanicalTurk::Transport which ISA Net::Amazon::MechanicalTurk::BaseObject which has a sub "new".

I have all of the required modules installed, as verified by the mturk_install.pl script. I've checked the issues on the module's CPAN page, but these errors are not addressed.

Has anyone had these problems and come up with any solutions? If you're successfully using this module, which version of Perl are you running?

Answer 1

The CPAN Testers had a similar experience.

Answer 2

You should submit a bug report to CPAN bugtracker's queue for Net::Amazon::MechanicalTurk

Answer 3

According to CPAN Testers, the latest version of Perl which worked with Net::Amazon::MechanicalTurk was 5.8.9. I built a local copy for use with this specific module.

Answer 4

I've build a small patch that helps solve this problem. There's an error in the internal logic of the library which prevented all the modules from loading properly. Check out the patch and my description at http://daveviner.blogspot.com/2009/12/amazon-mechanical-turk-perl-library.html

Answer 5

I've applied Dave Viner's patch and two of the patches in the RT queue. There's an unauthorized release with version 1.01_01 in my CPAN directory. I'll check the CPAN Testers response for the fixes and work on an official release after that. If you're the original author, please contact me.
