Personally I rebuilt everything on my system because I wanted everything |
15 |
to be compiled under my shiny new toolchain. I accomplished it via this: |
16 |
|
17 |
# emerge -eav system |
18 |
# emerge -eav world |

However, I don't believe you _have_ to rebuild. GCC 4.1 and 4.2 should |
21 |
be binary compatible. I know that my GCC 4.1 LibTorrent works fine with |
22 |
a GCC 4.2 built rtorrent, so I would like to say it should work fine. |
