| Code: | ~# xz
xz: /lib64/liblzma.so.5: version `XZ_5.6.0' not found (required by xz) |
XZ somehow broke, tried removing. and reinstalling it, no joy, can't update anything because Portage packages are all XZ archives (aside from XZ itself, which is a GZ archive for obvious reasons), any idea what's causing this? |

Please share emerge --info.
What happens when you reinstall xz? Does it build and install fine, just still doesn't work? |

| Also show the output of emerge --pretend --verbose app-arch/xz-utils, so we can see exactly which xz you are using and its options. I ask since some people applied local masks in the wake of the xz backdoor, and may still have those masks active now. |

Considering that current xz-utils installs to /usr/lib64 (not /lib64 regardless of split or merged-usr), this sounds like either a old version or potentially orphaned library assuming that this is not a merged-usr system (haven't seen emerge --info yet) |

Ionen: I didn't catch that it was looking in /lib64/ at all, renaming the liblzma.so.5 instance located there so XZ can't find it immediately fixed XZ
Would it be fine to replace /lib64 with a softlink to /usr/lib64 like /lib32 is a softlink to /lib so programs stop trying to use massively outdated libraries? |

No, because there should not be any massively outdated libraries in /lib64. Portage manages that directory, so if you have stale files in that directory, something is very wrong and needs to be fixed.
On my current amd64 system, /lib32 does not exist at all. It is not a symlink to anything. Therefore, it is strange to me that you have it as a symlink to /lib. Is this a very old system? What is the output of namei -l /{,usr/}{lib,lib32,lib64}; emerge --info? |
