Full Text Bug Listing

I had precompiled perl-5.8.8-r2 installed (from some stage) and it worked fine,
but I updated to 5.8.8-r3 and now @INC is wrong. It is missing 'perl5'
directory.
For example: (@INC contains: /etc/perl
/usr/lib64/vendor_perl/5.8.8/x86_64-linux /usr/lib64/vendor_perl/5.8.8
/usr/lib64/vendor_perl /usr/lib64/site_perl/5.8.8/x86_64-linux
/usr/lib64/site_perl/5.8.8 /usr/lib64/site_perl /usr/lib64/5.8.8/x86_64-linux
/usr/lib64/5.8.8 /usr/local/lib/site_perl .) where it should be
/usr/lib64/perl5/*
perl-cleaner all did not do anything,
revdep-rebuild did not help.
What should I do?

Reproducible: Always

Steps to Reproduce:
1. Run a perl script which use;s an external module
2.
3.

Actual Results:  
perl fails, and shows @INC being incorrect

Expected Results:  
the module is use;d normally

Please post your emerge --info. Also, looks just fine here:

$ perl -e "print @INC";
/etc/perl /usr/lib/perl5/vendor_perl/5.8.8/i686-linux
/usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl
/usr/lib/perl5/site_perl/5.8.8/i686-linux /usr/lib/perl5/site_perl/5.8.8
/usr/lib/perl5/site_perl /usr/lib/perl5/5.8.8/i686-linux /usr/lib/perl5/5.8.8
/usr/local/lib/site_perl .

fix install path on amd64

The patch perl-5.8.8-libbits.patch is broken. It relocates perl to
"/usr/lib64/5.8.8" on amd64.

solar, your patch...

  18 Nov 2007; <solar@gentoo.org> -files/perl-5.8.8-lib64.patch,
  +files/perl-5.8.8-libbits.patch, perl-5.8.8-r2.ebuild,
  perl-5.8.8-r3.ebuild:
  - fixed the lib64 patch that was breaking on amd64 32ul.

*** Bug 199525 has been marked as a duplicate of this bug. ***

b0rkage w/ libbits patch confirmed on ppc and x86 - can we please get rid of
that patch soonish for now and test a fixed patch in a -r4 testing version? :)

qa (or pretty much anyone) - reverting this patch swiftly would be mostly
appreciated, since we don't have any usable perl ATM...

Hang on a sec.

*** Bug 199563 has been marked as a duplicate of this bug. ***

Reverted.

Thanks! 

I suppose we'll unfortunaly need a revbump for Bug 198196 and to force
consistency as well, messing with things w/o revbump sucks :(

Mike D,
How did this patch break on amd64?

How did this break on x86? "" defaults to "lib"

All I see. Thanks for the patch. I'll merge this one next..

I'd strongly suggest that you check w/ perl people before *ever* touching this
ebuild again.

perl team is dead. releng and amd64 leads both approved and requested I merge
this 
to perl. ppc64 confirmed it did not break before anything was merged. 
It is unfortunate that non multilib users ran into problems. I hope all can
recover without much effort.

This has nothing to do w/ non-multilib, as said on this bug, you killed perl
for every single arch out there.

Plus, perl team is not dead, as proved on this bug, a dead team hardly would
react faster than someone who's responsible for a completely broken patch.

Jakub, Please take the argumentative attitude and rude comments elsewhere.

argumentative == screw-up confirmed by everyone out there?
rude comments == asking you to follow the policies and stop touching stable
ebuilds (which broke everyone out there, and interfered with release as well)?

*If* anyone tested this, they would have discovered that this totally kills
perl. This is an apparent breach of QA and ebuild policies, not to mention
common sense. What was the reason to mess w/ dev-lang/perl--5.8.8-r2 as well?

Not really what more to say here, I'd expect that you'd apologize to perl folks
at minimum, but that apparently isn't the case. :/

*** Bug 199635 has been marked as a duplicate of this bug. ***

Could this please get a revbump perl to ensure anybody who merged the broken r3
gets a fixed version?

Revbumped.

Modules installed after dev-lang/perl-5.8.8-r3 are borked. For example after
upgrading to dev-lang/perl-5.8.8-r4 amavisd-new was still complaining about
missing modules for example.

Here's my quick and dirty solution that could help others get their perl back
on its feet again:

1/ a one liner based on eix, which is fortunately a quick install if you miss
it and don't want to hack around emerge --search (ignore carriage-returns if
any):
eix -IAnc* perl |awk '{print $2}'|egrep -v
'virtual|dev-lang|libperl|perl-cleaner'
| for i in `cat -`; do echo -n "$i "; done

to get the list of perl modules in a copy-paste ready list

2/ emerge -1av <pasted_list>

Now amavisd-new works again.

Wow, major borkage, too bad I had a list of perl modules waiting for upgrade
when r3 was commited...

If you have lots of modules and can hack a script quickly, parsing
/var/log/emerge.log for modules emerged after r3 should do it.
