[gentoo-user] Cleaning up perl

[gentoo-user] Cleaning up perl

I've found myself in a mess with perl (see other thread).  In the process I
discovered what appears to be a bunch of old versions of perl-related
things.  In /usr/lib/perl5, there are subdirectories over 4 years old.
Here's the complete list

5.8.2  5.8.4  5.8.5  5.8.6  5.8.7  5.8.8  site_perl  vendor_perl

The current perl version is 5.8.8.  The versions 5.8.2 and 5.8.4 date from
2004.

Can I safely just delete them?

Not really.
But gentoo provides a tool to sort it.

Interesting.  I did not know about this cleaner.

Unfortunately, while it tries to do a number of things, they all fail in the
same way: a problem with Errno.pm.
I guess using perl to clean up perl is not all that robust in this case.

I still prefer good old cpan over gentoo' g-cpan to mainatain perl modules.

Before upgrading perl, fire up cpan, create a bundle file of all your 
installed modules using the autobundle command and after the upgrade, start 
cpan again and run "install Bundle::Snapshot-<date>".

I also use it to keep installed perl modules uptodate. Just use the "upgrade" 
command in cpan.

If you did this, you can simply remove the old 5.8.x directories.

It's too late for me now to do any of that.  I'm hosed.
I can build perl, but I cannot run perl-cleaner.  I can't run h2ph.  There
are probably
a bunch of other things I can't do also.

Accordingly, I'm renaming the offending Errno.pm, knowing that there's
another more
recent one around.  I'm hoping that it's located by @INC or some such.

At the moment, it seems to be working.

No, not really. You only need perl to run cpan.

You don't need to. Remove the old 5.8.x directories and install the modules 
you had installed there again (if needed), using cpan this time. You can find 
out which packages were installed by searching for files named ".packlist". 
Each directory which contains such a file corresponds to one perl module.

Eventually re-emerge perl after removal of the old directories. This should 
clean up your perl installation.

I eventually got most things back by removing the site-perl version of
Errno.pm (installed by CPAN sometime in the past, I think.)  There was
another, more recent version which was apparently found automatically,
allowing things to proceed.  I have also removed a bunch of other things
that were in site-perl, especially everything I could replace with a version
from portage.

I have now been able to run 'perl-cleaner reallyall', and have rebuilt perl
both with and without the ithreads USE-flag (see separate thread).  So I
suppose I'm now in good shape. CPAN also works, though I'm a bit reluctant
to use it since that's how I got in this mess in the first place.  I'd
rather rely on portage to keep things current and consistent.   Hmmmm.
Does anyone know how to run CPAN in a cron job, just enough to run the 'r'
command?  I do that with portage to tell me when I have to worry about
revdep or depclean.

CPAN is not just an interactive program, but also a normal perl module which 
you can use in your on scripts. So you could write a perl script and let 
it "use CPAN" so that it can do any CPAN operation you want. See "perldoc 
CPAN" for the details.
