emerge--info

ebuild for virtual/libnet-1.230.0 was stabilized on many architectures and has 

RDEPEND="|| ( =dev-lang/perl-5.18*

Now Portage-2.2.1 demands to have perl-5.18.1, which breaks dependencies to many packages.

So how does it not work? Portage should be able to figure out that one ...

> So how does it not work? Portage should be able to figure out that one ...

It does apparently not figure it out. Today my daily `emerge --update --deep --ask world` asked to update virtual/perl-libnet to a more recent stable version, pulling perl-5.18.1 at the same time, and creating conflicts to the many packages which are not ready for perl 5.18. 

I might mask either of virtual/perl-libnet-1.230.0 or devl-lang/perl-5.18.1, but I think it's the very purpose of setting ACCEPT_KEYWORDS according to my taste to avoid doing manual masking/unmasking of packages.

Here is what I get when I want to update my system to latest stable perl-libnet:

emerge --ask virtual/perl-libnet
These are the packages that would be merged, in order:

I repeated with --backtrack=30 and this is what I get:

$ emerge --ask --update --deep world --backtrack=30
This action requires superuser access...
Would you like to add --pretend to options? [Yes/No] y

"setting ACCEPT_KEYWORDS according to my taste"


You unmasked dev-lang/perl for the stable branch? Mixing the stable and unstable branch is unsupported. Try unmasking more packages.

That's right, my bad. (I did that for dev-lang/rakudo and forgot about it). Everything is fine then, this entry is INVALID.
