Probably not. I would do an emerge -a --depclean. If nothing depends on |
| 21 |
the old gcc, it will be removed. Otherwise you get a message what has to |
| 22 |
be rebuilt, like I do: |
| 23 |
|
| 24 |
weird ~ # emerge -a --depclean |

* Always study the list of packages to be cleaned for any obvious |
| 27 |
* mistakes. Packages that are part of the world set will always |
| 28 |
* be kept. They can be manually added to this set with |
| 29 |
* `emerge --noreplace <atom>`. Packages that are listed in |
| 30 |
* package.provided (see portage(5)) will be removed by |
| 31 |
* depclean, even if they are part of the world set. |
| 32 |
* |
| 33 |
* As a safety measure, depclean will not remove any packages |
| 34 |
* unless *all* required dependencies have been resolved. As a |
| 35 |
* consequence, it is often necessary to run `emerge --update |
| 36 |
* --newuse --deep @world` prior to depclean. |

* In order to avoid breakage of link level dependencies, one or more |
| 42 |
