Sometimes a package has to depend on a specific version of a slotted package being the "active" one to build correctly, like in the current "tr1" discussion on -dev [1] or with packages that depend on the running kernel. |

Currently this isn't really possible, however I while ago I got an idea how to solve this. Keep in mind this is just a rough idea and I'm pretty sure some people can/will point out why it is a stupid idea, but anyway: |

The idea is to add a special category (let's call it "active" for now) that has the following properties: |
| 6 |
- this category doesn't exist in portdir or vdb (= no ebuilds) |
| 7 |
- when portage ($pkgmanager) encounters a "active/foo" atom in a dependency string it executes some special code (e.g. "$PORTDIR/scripts/active-check/foo =active/foo-1") to determine if that atom is satisfied |

(and yes, this kinda goes with multi-repo/multi-format support) |
