Thanks for the response! I see now. I think the problem from my |

perspective then is that the docs need to be updated a bit, as they |
3 |
all point to the 'experimental' sections of the mirrors, which only |
4 |
contain old 970-targeting ps3 stage4's. I see now that 'releases' has |
5 |
more generic stage3's suitable for rebuilding specifically for |
6 |
Cell/BE. |
