Running an application using Email::Sender::Simple results in: Attempt to reload Email/Sender/Simple.pm aborted. http://stackoverflow.com/questions/2202243/why-does-a-module-compile-by-itself-but-fail-when-used-from-elsewhere suggests that this error is due to a compilation problem with the module. perl -c /usr/lib/perl5/vendor_perl/5.16.3/Email/Sender/Simple.pm results in Can't locate MRO/Compat.pm in @INC (@INC contains: /home/paul/lib/perl /home/paul/Trading/lib /home/paul/Trading/lib /home/paul/Betting/lib /home/paul/Betting/betfairfree/lib /etc/perl /usr/local/lib/perl5/5.16.3/i686-linux-thread-multi /usr/local/lib/perl5/5.16.3 /usr/lib/perl5/vendor_perl/5.16.3/i686-linux-thread-multi /usr/lib/perl5/vendor_perl/5.16.3 /usr/local/lib/perl5 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.16.3/i686-linux-thread-multi /usr/lib/perl5/5.16.3 .) at /usr/lib/perl5/vendor_perl/5.16.3/i686-linux-thread-multi/Class/MOP.pm line 15. emerge -av dev-perl/MRO-Compat resolves. => dev-perl/Email-Sender should depend on dev-perl/MRO-Compat...
IMHO Seems like this is not Email::Sender issue. Look at > at /usr/lib/perl5/vendor_perl/5.16.3/i686-linux-thread-multi/Class/MOP.pm line 15. AFAIK Email::Sender use Moo. And seems like you have Moose also (because Class::MOP comes with it). And Moo try to load Class::MOP which require MRO::Compact. So the question: How was installed all those modules? Do you have them all?
Having Class::MOP installed but not MRO::Compat means you've not installed all the dependencies of dev-perl/Moose properly. dev-perl/Moose provides Class/MOP.pm dev-perl/Moose depends on MRO/Compat.pm Therefore, you appear to have a broken perl install and you need to run perl-cleaner. I have reason to believe you *already* had dev-perl/MRO-Compat installed, however, installed on a previous perl, thus, a re-installation caused it to be installed on your current perl.
I take your point that the error was actually coming from Class::MOP, not Email::Sender::Simple. This issue did happen amid the debris of a nightmare migration from perl 5.16 to 5.18, so things could easily have been in the wrong place... As a mere application user I definitely wish that the perl side of Gentoo could be easier. perl-cleaner is not a panacea, especially when perl itself refuses to install.. Thanks for your comments.
