I wrote the MakeMaker system so I was just cribbing off that. It made more
sense to build a list of directories to scan and then scan them than to add
individual file exceptions later. I could put it in a separate patch, but it
would require some bending.

Sorry. I have lots of experience with git but very little with the email
submission tools. I've always either just done everything via repositories or
It sounds like I should figure out the git-send-email tool and do this very

Nope, just copy .pm files in.

No idea, this is my first look at the code, but now it's possible. In my
experience, if there's a barrier to using CPAN modules then people won't use
them. They'll rewrite the functionality poorly.

The man page is now man3/bundles::Error::Error.3 which is equally as incorrect
as man3/private-Error.3. It is possible to correct that so it's man3/Error.3,
but that's going to require some effort. Basically its in the same boat as
PM. Once you have to change one you have to change them all.
Why do install scripts have specific code to look for that man page?
If it's going to be trouble I can put Error.pm back. It's just something I
did in passing.

Ideally, that second Makefile would go away. Parallel build systems are extra
work and generate bugs.
The log suggests it might have something to do with people wanting to build
with an ActiveState Perl on Cygwin or something? MakeMaker builds different
Makefiles depending on the OS, so it may be as simple as telling Makefile.PL
what flavor of make you're using.
