Should probably instruct users to upgrade all packages first because it |
| 11 |
can be, as I’ve experienced, nearly impossible to upgrade GCC if the |
| 12 |
world isn’t up to the latest stable. |

An ‘emerge -avuDN world’ should do the trick as a first step. |

Some of these can take a while. Maybe we want to spell it out: |
| 24 |
|
| 25 |
for p in sys-devel/gcc:6.4.0 sys-devel/binutils sys-libs/glibc; do |
| 26 |
emerge -1 $p || break |
| 27 |
done |
