Intrepid has asked for the wisdom of the Perl Monks concerning the following question:

I've been trying to install a Bundle:: made on an older computer, to a newer one with a pristine perl installation. I'm running into repeated fails when I get to Module::Package and I am hoping for one or more of two things to happen: (a) just by writing out what seems to be happening I'll have a burst of enlightenment, or (b) someone reading this will provide answers that lead to success.

The system is Cygwin on Windows 11, perl version 5.40.3 ("system" perl for an up to date Cygwin).

Here's some of what I see in the terminal:

  INGY/Module-Install-ManifestSkip-0.24.tar.gz
Tests succeeded but one dependency not OK (Module::Manifest::Skip)
  INGY/Module-Install-ManifestSkip-0.24.tar.gz
  dependencies -- NA
  INGY/Module-Package-0.30.tar.gz
  Has already been unwrapped into directory /cygdrive/D/var/cache/builds/CPAN/Module-Package-0.30-2
  INGY/Module-Package-0.30.tar.gz
  Has already been prepared
Running make for I/IN/INGY/Module-Package-0.30.tar.gz
Warning: Prerequisite 'Module::Install::ManifestSkip => 0.19' for 'INGY/Module-Package-0.30.tar.gz' failed when processing 'INGY/Module-Install-ManifestSkip-0.24.tar.gz' with 'make_test => NO one dependency not OK (Module::Manifest::Skip)'. Continuing, but chances to succeed are limited.

It's a bit unfortunate that the module names are so similar. It makes my eyes cross when I try to scan the output.

Fail point:

Re: Strange depedency dilemma with Module::Package install

    Have you tried looking into the log, or installing Module::Manifest::Skip manually to see what errors it shows? Also, the testers' page doesn't give much optimism.

    Most of the time, the errors seem to be: 

    Can't locate object method "_install_subs" via package "Module::Manife
+st::Skip" at .../lib/site_perl/5.42.0/Moo.pm line 49.
BEGIN failed--compilation aborted at t/TestModuleManifestSkip.pm line 
+6.

    Update:

    _install_subs was added to Moo in 2.004000, so tests using an older versions of Moo pass.

    Update 2:

    It seems the else branch is no longer needed on line 31 of Skip.pm with Moo 2.004+.

    It has already been reported.
