Bug 453268 – dev-lang/perl-5.16.2 causes dependency conflict with all perl modules

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Mike Gilbert 2013-01-21 03:02:35 UTC]

By setting EAPI=5, the ebuild triggers stricter handling of IUSE, causing errors like this:

WARNING: One or more updates have been skipped due to a dependency conflict:

dev-lang/perl:0

  (dev-lang/perl-5.16.2::gentoo, ebuild scheduled for merge) conflicts with
    dev-lang/perl[-build] required by (dev-perl/Net-HTTP-6.30.0::gentoo, installed)
  (dev-lang/perl-5.16.2::gentoo, ebuild scheduled for merge) conflicts with
    dev-lang/perl[-build] required by (dev-perl/Encode-Locale-1.30.0::gentoo, installed)
  (dev-lang/perl-5.16.2::gentoo, ebuild scheduled for merge) conflicts with
    dev-lang/perl[-build] required by (perl-core/IO-1.25::gentoo, installed)
  (dev-lang/perl-5.16.2::gentoo, ebuild scheduled for merge) conflicts with
    dev-lang/perl[-build] required by (dev-util/App-SVN-Bisect-1.1::gentoo, installed)

Possible resolutions are:

1. Add build to IUSE in dev-lang/perl-5.16.2

2. Change the dependency to "dev-lang/perl[-build(-)]" in perl-module.eclass and upgrade all perl modules to EAPI >= 4

3. Downgrade perl-5.16.2 to EAPI 4 temporarily

4. Add "build" (and maybe "bootstrap" for consistency) to IUSE_IMPLICIT variable in gentoo-x86/profiles/base/make.defaults.

I am tempted to choose a) add "build" to perl-5.16.2 and remove it once the older ebuilds are gone.

But I cannot fix it right now. If anyone wants to, just do it.

I choose option 1 and just moved it to my local overlay. Worked like a champ. defaults to disabled anyway (-build)

(In reply to comment #2)

Sounds good to me. Committed.

It's unclear to me how to exactly resolve the problem.  I've synced the new ebuild but when I try to emerge it with the build flag all my perl modules complain, for example, 

    dev-lang/perl[-build] required by (dev-perl/libxml-perl-0.80.0::gentoo, installed)

Is there a workaround for this?

[Comment 7 Torsten Veller (RETIRED) 2013-01-27 13:48:32 UTC]

"build" is only used in early stage building.

Do emerge dev-lang/perl with USE="-build".
