Indeed. I'm very interested in hearing whether it works for you. |

That's a problem we should fix in portage (the prefix portage doesn't run |
| 15 |
ldconfig, but the RAP version should). The above bootstrap script currently |
| 16 |
does a workaround, but it's a fragile temporary solution. |

The version included in the overlay used by the bootstrap script should have |
| 23 |
fixed problems with perl linking against the wrong libraries. The keyword |
| 24 |
here is "should" -- it would not surprise me at all if this is still flaky. |

This is fixed in the bootstrap overlay. |

This is also fixed in the bootstrap overlay. |

So far, we've accumulated all known required patches in the overlay used by |
| 44 |
the bootstrap script, at https://github.com/redlizard/prefix-libc/ . We are |
| 45 |
working on merging those changes to the appropriate places. The bootstrap |
| 46 |
script uses this overlay, but it should go away soon. |
