When using emerge to download the sources for multiple versions of a package, it now errors out with: $ emerge --fetchonly =gentoolkit-dev-0.2.6.1 =gentoolkit-dev-0.2.5 Calculating dependencies \ !!! Multiple versions within a single package slot have been !!! pulled into the dependency graph: ('ebuild', '/', 'app-portage/gentoolkit-dev-0.2.5', 'merge') (no parents) ('ebuild', '/', 'app-portage/gentoolkit-dev-0.2.6.1', 'merge') (no parents) While I think this behavior is correct in the sense that you have an invalid depgraph. It is a regression from previous versions and loss of convenience.
