[Chicago-talk] Undefined subroutine Class::MOP::Mixin::HasMethods::wrap/body errors

[Sean Blanton]

The errors all come from use and require statements, so they are compile
errors, not runtime. Also getting this one:

Undefined subroutine &Package::DeprecationManager::_HASH called at
/usr/local/share/perl5/Package/DeprecationManager.pm line 18.
BEGIN failed--compilation aborted at
/usr/local/lib64/perl5/Moose/Deprecated.pm line 22.
Compilation failed in require at /usr/local/lib64/perl5/Moose.pm line 14.
BEGIN failed--compilation aborted at /usr/local/lib64/perl5/Moose.pm line
14.
Compilation failed in require at <path>/<class> line 2.


In this, the line 2 at <path>/<class> is 'use Moose;'

Regards,
Sean
