The perl-core ebuilds overrides the perl-core modules such that you can update them without recompiling dev-lang/Perl.</p> <p>Each perl-core module has a corrensponding virtual/perl-* package. The virtual category is used by portage when emerging to take into account that a module can be either provided by dev-lang/perl package or found in perl-core category.</p> <p>So, what to do in case of blocks when upgrading your Gentoo machine?</p> <p>Perl-cleaner is a package provided to get rid of these blocks and to migrate from perl-core to virtual/perl-*.</p> <pre class="wp-code-highlight prettyprint linenums:1">emerge perl-cleaner emerge dev-lang/perl perl-cleaner --all</pre> <p>if you still have problems when upgrading @world you add a backtrack option</p> <pre class="wp-code-highlight prettyprint linenums:1">emerge -uDN --backtrack=30 @world</pre> <p>or you can unmerge all perl-core packages and then finally upgrade world</p> <pre class="wp-code-highlight prettyprint linenums:1">emerge --unmerge perl-core/*</pre> <p>This will remove all perl-core packages that virtual/perl-* packages will bring back if needed.</p> <p style="text-align: right;"> Francesco Mecca </p>emergeGentooperlperl-corePesceWandaportage conflictvirtual/perlfrancescomecca.eu/blog/2015/9/11/about-perl-packages-in-gentoo/Fri, 11 Sep 2015 12:52:25 GMT
