Bug 302586 – libperl and perl ithreads and perl-cleaner

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Dmitry Ivankov 2010-01-28 09:32:25 UTC]

If you have perl and libperl installed and then decide to change ithreads useflag, remerge them then you'll have to remerge some packages with perl-cleaner. My suggestion is to add a note about it in the perl and libperl ebuilds.

Reproducible: Always

Steps to Reproduce:
1. have a system with USE=-ithreads perl, libperl and vim installed
2. USE=ithreads emerge libperl perl
3. vim

Actual Results:  
vim: symbol lookup error: vim: undefined symol: PL_curpad

Expected Results:  
vim is started

Vim is just an illustration, the issue is that it's hard to find out that there is this nice perl-cleaner, so we should tell about it on remerging perl on ithreads flag change. Otherwise user will have "random" packages broken(remerge needed).

That's already in perl-5.10.1.

Nice :), what about porting it to stable perl-5.8.8?

I didn't do it because i didn't wanted to bump EAPI for that old version.
