Did you try the new revdep-rebuild in case it works (better)? |

I am not familiar with the particular software and wouldn't know how to keep |
| 54 |
it alive on a present day Gentoo system - other than building Gentoo using an |
| 55 |
old snapshot and installation media, perhaps in a VM and using additional |
| 56 |
packages of the same era from the attic in a local overlay. |

Someone else may be able to offer useful advice, but I would think this is |
| 59 |
more of a question suitable for the gentoo-dev mailing list[1] and IRC |
| 60 |
channel[2]. Have you tried asking there? |
