Bug 224577 – dev-lang/perl has wrong @INC order

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michele Beltrame 2008-06-02 08:03:28 UTC]

dev-perl/perl-5.10.0, once installed, features this @INC:

  @INC:
    /usr/lib/perl5/5.10.0/x86_64-linux
    /usr/lib/perl5/5.10.0
    /usr/lib/perl5/site_perl/5.10.0/x86_64-linux
    /usr/lib/perl5/site_perl/5.10.0
    /usr/lib/perl5/site_perl/5.8.8
    /usr/lib/perl5/site_perl/5.8.7
    /usr/lib/perl5/site_perl
    /usr/lib/perl5/vendor_perl/5.10.0/x86_64-linux
    /usr/lib/perl5/vendor_perl/5.10.0
    /usr/lib/perl5/vendor_perl/5.8.8
    /usr/lib/perl5/vendor_perl/5.8.7
    /usr/lib/perl5/vendor_perl

This makes it impossible to automatically use perl-core modules which version is newer than 5.10, as they're installed into vendor_perl and that path is searched *last*.

Perl 5.8.8 has the correct @INC ordering:

    /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/5.8.7
    /usr/lib/perl5/vendor_perl/5.8.7/i686-linux
    /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/5.8.7
    /usr/lib/perl5/site_perl/5.8.7/i686-linux
    /usr/lib/perl5/site_perl
    /usr/lib/perl5/5.8.8/i686-linux
    /usr/lib/perl5/5.8.8
    /usr/local/lib/site_perl

There is no such package as dev-perl/perl. Furthermore, I couldn't find a version 5.10.0 for the existing dev-lang/perl. Did you install this version from some overlay?

[Comment 2 Michele Beltrame 2008-06-02 15:28:42 UTC]

Yes, it's dev-lang/perl - sorry for the mistake.

As per summary,it's in the Perl overlay not in the official Portage. I somehow thought Bugzilla could be used also for official overlays. If not, sorry. ;)

[Comment 3 Sergiy Borodych 2008-06-04 12:15:25 UTC]

ok
I think it here

# diff dev-lang/perl/perl-5.8.8-r5.ebuild /usr/local/portage/layman/perl-experimental/dev-lang/perl/perl-5.10.0.ebuild
...
90c82,84
< 	cd "${S}"; epatch "${FILESDIR}"/${P}-reorder-INC.patch
---
> 
> 	# TODO: Holy crap, we'll need to re-patch this.
> 	#cd ${S}; epatch ${FILESDIR}/${P}-reorder-INC.patch

so waiting for re-patching :)

[Comment 4 Fabian Groffen 2008-06-13 21:42:54 UTC]

Please base your overlay's ebuild off of the latest gentoo-x86 one, it's hopelessly outdated.

Consider de-prefixing my prefix version of libperl-5.10.0, with fixed patches (instead of just commenting them out).  Look at http://overlays.gentoo.org/proj/alt/changeset/25414, you might in particular be interested in http://overlays.gentoo.org/proj/alt/browser/trunk/prefix-overlay/sys-devel/libperl/files/libperl-5.10.0-reorder-INC.patch?rev=25414

Perl team, any chance we can get this rolling into gentoo-x86 soon?

With above mentioned patch:

  Built under darwin
  Compiled at Jun 15 2008 13:38:05
  @INC:
    /etc/perl
    /Library/Gentoo/usr/lib/perl5/vendor_perl/5.10.0/darwin-2level
    /Library/Gentoo/usr/lib/perl5/vendor_perl/5.10.0
    /Library/Gentoo/usr/lib/perl5/vendor_perl/5.8.8
    /Library/Gentoo/usr/lib/perl5/vendor_perl
    /Library/Gentoo/usr/lib/perl5/site_perl/5.10.0/darwin-2level
    /Library/Gentoo/usr/lib/perl5/site_perl/5.10.0
    /Library/Gentoo/usr/lib/perl5/site_perl
    /Library/Gentoo/usr/lib/perl5/5.10.0/darwin-2level
    /Library/Gentoo/usr/lib/perl5/5.10.0
    /usr/local/lib/site_perl
    .

Looks pretty much as "correct" order to me.

[Comment 6 Torsten Veller (RETIRED) 2009-08-08 09:10:07 UTC]

I'd propose to change this to:
site > vendor > core

And ebuilds should only install to vendor and local changes go to site.

Patches for this change should be in `blead`

[Comment 7 Torsten Veller (RETIRED) 2009-09-28 18:03:04 UTC]

Fixed for perl-5.10.1: site > vendor > core
