When I have perl 5.10.1 installed I have core module threads::shared v1.29, but dev-perl/Thread-Queue wants to install >=virtual/perl-threads-shared-1.21. BTW same with dev-perl/Thread-Semaphore Reproducible: Always Steps to Reproduce:
Please provide emerge --info and the config.log (or other logs if it doesn't fail during ./configure).
Well, emerge --info and compilation is not relevant. Main issue is that portage wants to install package dev-perl/perl-threads-shared, which provide perl module threads::shared, when I allready have one (provided by perl 5.10.1, package dev-lang/perl). I can unmask package dev-perl/perl-threads-shared and everything will be ok (from portage's pov). But I didn't must to install that package to get working Thread::Queue module, as I allready have threads::shared with perl 5.10.1. For example, if I decide to install Thread::Queue via perl cpan shell then cpan will install only Thread::Semaphore by dependence, but not threads::shared . Hmm, may be providing of virtual modules (such as virtual/perl-threads-shared) by package dev-lang/perl will be enough to resolve this issue?

Well, it doesn't work as you expect. If threads::shared v1.29 is part of perl-5.10.1, then virtual/perl-threads-shared-1.29 depends on either perl-5.10.1 or perl-core/threads-shared-1.29. virtual/perl-threads-shared-1.30 will only depend on perl-core/threads-shared-1.30 I've fixed the dependencies of the virtuals in the overlay. But the package manager uses the latest package, so often will the new package installed.
