Actually, you shouldn't even need to specify the version (which syntax, |
| 26 |
btw, is 'emerge -C =net-ftp/vsftpd-2.0.3-r1' --you need that = sign to |
| 27 |
specify a particular version of a program), just doing a regular |
| 28 |
|
| 29 |
emerge -C(av) vsftpd |
| 30 |
|
| 31 |
should be perfectly sufficient to clear the block. |

You likely should not have to. The idea of a BLOCK is that the new |
| 39 |
package either replaces the functionality of, or includes the |
| 40 |
functionality of, the currently installed program. |
| 41 |
|
| 42 |
This is why they block each other; for example, xchat-gnome is blocked |
| 43 |
by xchat, because xchat-gnome is the full xchat program (as opposed to a |
| 44 |
frontend), as is xchat (of course). So you can't install both of them at |
| 45 |
the same time. |
| 46 |
|
| 47 |
In this case, ftpbase installs the same functionality as vsftpd-- and |
| 48 |
may in fact create binaries with the same name, as gamin does for fam. |
| 49 |
|
| 50 |
You can't (apparently) have two ftp daemons installed at the same time, |
| 51 |
just as you can't have two file alteration monitors installed at the |
| 52 |
same time. |
| 53 |
|
| 54 |
I admit, the message is confusing, but just remember it's in reverse |
| 55 |
from what seems to naturally make sense to people: |

means that because |
| 63 |
|
| 64 |
net-ftp/vsftpd-2.0.3-r1 |
| 65 |
|
| 66 |
is currently installed on the system |
| 67 |
|
| 68 |
net-ftp/ftpbase-0.00 |
| 69 |
|
| 70 |
which would be installed by the current operation, under normal |
| 71 |
circumstances, cannot be installed. |
| 72 |
|
| 73 |
Thus, the first package named is installed and has to be removed so that |
| 74 |
the second package named can be installed by Portage. |
| 75 |
|
| 76 |
Most people (including me, before I trained myself) read this message |
| 77 |
the other way around and think that the second package named is the one |
| 78 |
that is currently installed, but the second named package is the one |
| 79 |
that Portage *wants* to install (but can't, because of the first named |
| 80 |
package). |
