Description Zac Medico gentoo-dev 2010-09-29 19:00:42 UTC 
If you try to replace an old-style virtual with new provider, it doesn't resolve virtual blocks because dependencies remain bound to the old provider. For example, when trying to replace mail-mta/exim with mail-mta/ssmtp:

Calculating dependencies... done!
[ebuild  N    ] mail-mta/ssmtp-2.62-r8  USE="ipv6 ssl -maxsysuid -md5sum" 56 kB
[blocks B     ] mail-mta/exim ("virtual/mta" is blocking mail-mta/exim-4.72, mail-mta/ssmtp-2.62-r8)

Total: 1 package (1 new), Size of downloads: 56 kB
Conflict: 1 block (1 unsatisfied)

The delayed || evaluation code from bug 264434 should help in solving this bug, since it applies to all virtual dependencies.
Comment 2 Zac Medico gentoo-dev 2011-05-12 19:53:19 UTC 
Gentoo has recently stopped using old-style PROVIDE virtuals, so it won't be necessary to fix this.
