Well, due to the long compile times I was trying to get the dependencies |
| 26 |
resolved so I could run `emerge -auDNe world --exclude sys-devel/gcc |
| 27 |
--exclude sys-devel/llvm --exclude sys-devel/libtool --exclude |
| 28 |
sys-devel/binutils --exclude sys-libs/glibc --keep-going world` so it |
| 29 |
would recompile everything and update as it went along. (I had already |
| 30 |
built the excluded packages under the new profile with gcc6.) |
| 31 |
|
| 32 |
While I didn't remerge perl immediately after, it was included in the |
| 33 |
rebuild process of --emptytree. |
| 34 |
|
| 35 |
And it was successful! I only had perl blocking everything, so once I |
| 36 |
sledgeammered that update, it was able to calculate its dependency list, |
| 37 |
and it rebuilt all 500 installed packages (well, less the ones I |
| 38 |
excluded) successfully - no failed packages or anything, while upgrading |
| 39 |
as needed. It did take almost 30 hours though. |
| 40 |
|
| 41 |
When trying to get perl blockers to resolve I even tried --backtrack=200 |
| 42 |
and it still failed. That was try 5 or 6 and at that point I was getting |
| 43 |
annoyed and tried the sledgehammer technique. |
