Let's take the package gnome-extra/evolution-data-server-1.2.3. |
| 15 |
It depends on mozilla package only if the mozilla use flag is set (and |
| 16 |
ssl) - thus, you can see "ssl? ( mozilla? ( www-client/mozilla )" in the |
| 17 |
ebuild. |
| 18 |
I do not have "mozilla" use flag set, and evolution-data-server-1.2.3 is |
| 19 |
also compiled without this flag. |
| 20 |
However, when I run "equery depends mozilla", I get |
| 21 |
"gnome-extra/evolution-data-server-1.2.3". |
| 22 |
Note that "equery depgraph evolution-data-server" does not show mozilla, |
| 23 |
so this works correctly. |

I do understand that they don't depend on xorg-x11, but on the xirtual |
| 42 |
package. |
| 43 |
However, since "equery depends xorg-x11" shows nothing, I might think |
| 44 |
that it's safe to remove it - I have no way of knowing that this will |
| 45 |
break all packages that depend on x11. |
| 46 |
So, what is a potential enhancement from your point of view is really a |
| 47 |
bug from mine - it's useless to know the direct dependencies on a |
| 48 |
package if I do not know the "hidden"dependencies through virtual |
| 49 |
packages. Note that qpkg worked correctly, showing dependencies on |
| 50 |
virtual packages as well. |
