Description Michael Mounteney 2011-07-10 20:22:19 UTC 
Attempting to emerge the package leads to a circular dependency.  Since none of the packages have any use flags, it is not possible to break the cycle in the usual way, by building with some use flags omitted.

pimple / # emerge perl-ExtUtils-MakeMaker
Calculating dependencies... done!

 * Error: circular dependencies:

(perl-core/CPAN-Meta-2.110.930::gentoo, ebuild scheduled for merge) depends on
 (virtual/perl-ExtUtils-MakeMaker-6.580.0::gentoo, ebuild scheduled for merge) (buildtime)
  (perl-core/ExtUtils-MakeMaker-6.580.0::gentoo, ebuild scheduled for merge) (runtime)
   (virtual/perl-CPAN-Meta-2.110.930::gentoo, ebuild scheduled for merge) (buildtime)
    (perl-core/CPAN-Meta-2.110.930::gentoo, ebuild scheduled for merge) (runtime)

 * Note that circular dependencies can often be avoided by temporarily
 * disabling USE flags that trigger optional dependencies.

Comment 1 Marc-Antoine Perennou 2011-07-10 21:42:59 UTC 
While waiting for a fix, you can still install the previous version of virtual/perl-ExtUtils-MakeMaker and perl-core/ExtUtils-MakeMaker and then you should be able to upgrade it without the circular dependency blocking you
Comment 2 Mike Gilbert gentoo-dev 2011-07-11 01:38:55 UTC 
Confirmed with ACCEPT_KEYWORDS="~amd64".
Comment 3 Benjamin Lee 2011-07-11 02:13:45 UTC 
Per comment #1 I worked around the issue by installing the older version of ExtUtils-MakeMaker, which does not depend on CPAN-Meta:

emerge -1av =perl-ExtUtils-MakeMaker-6.56 =ExtUtils-MakeMaker-6.56-r1
