I'm pretty sure this is an internal thing ( emerge builds a depgraph with the current system, not the system that would be present at the time that package foo gets built.

Fex.
livecd log # emerge -p syslog-ng vixie-cron screen postfix

These are the packages that I would merge, in order:

vixie-cron depends on virtual/mta.  Postfix provides virtual/mta.  However, postfix is not considered for the provide because it's after vixie-cron in the list of packages, when in fact it very well could be.

livecd log # emerge -p syslog-ng postfix vixie-cron screen

livecd log #

moving postfix before vixie-cron fixes things, because portage assumes previously specified packages will install correctly.

I talked to Jstubbs about this, and I figured I'd file a bug on it to make sure it gets in the new happy version of the dep-resolver and things.  Also it should  give a reference to anyone else looking for the same type of deal.
