If this is a dup, I honestly couldn't find it.
I was working on g-cpan this week and came across this troubling bug. Here's the output:
These are the packages that would be merged, in order:
Calculating dependencies /
!!! Multiple versions within a single package slot have been
!!! pulled into the dependency graph:
('ebuild', '/', 'virtual/perl-Test-Simple-0.66', 'merge') pulled in by
('ebuild', '/', 'dev-perl/Test-Exception-0.24', 'merge')
('ebuild', '/', 'virtual/perl-Test-Simple-0.63', 'merge') pulled in by
('ebuild', '/', 'perl-gcpan/Class-Accessor-Chained-0.01', 'merge')
('ebuild', '/', 'perl-gcpan/Data-Page-2.00', 'merge')
('ebuild', '/', 'perl-gcpan/Module-CoreList-2.09', 'merge')
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be

Curious, I checked.
$ for item in "Module-CoreList/Module-CoreList-2.09.ebuild Class-Accessor-Chained/Class-Accessor-Chained-0.01.ebuild Data-Page/Data-Page-2.00.ebuild /usr/portage/dev-perl/Test-Exception/Test-Exception-0.24.ebuild "; do grep "Test-Simple" $item; done
So only one of these depended on a specific version, all are ~arch'd (as am i), and there isn't any clear reason why this is blocked based on the dep. Help :)
This seems like it may be related to the issue reported in bug 158358. Please post --debug output for the command that triggers the error.
and before you ask - block was too large for a comment field, and bugzie died when i tried attaching it as an attachment. such is my day.
Try this url since dev.g.o seems to be eating the file.
Since ~dev-lang/perl-5.8.8 is installed, preference algorithm is selecting virtual/perl-Test-Simple-0.63 even though a higher version is available. You can work around the problem by adding <=virtual/perl-Test-Simple-0.63 to your package.mask. I'm work on improving the preference algorithm now...

This is fixed in svn r5419.
This has been released in 2.1.2_rc4-r3.
Thank you :)
