Such that people can find this issue, here is the error message this fixes on macOS using GHC 8.8.1 (can occur during building or running): |

Previously the package conf files were handled without paying attention
to the fact that it's pretty-printed output. One problem was discovered
with GHC 8.8.1 on Darwin, where the dynamic-library-dirs first field
seems to have increased in length, meaning while before it was
dynamic-library-dirs: some-small-directory-name
some-more-directories
Now it is
dynamic-library-dirs:
some-larger-directory-name
some-more-directories
Which breaks the code installed for NixOS#25537,
because that assumed the former format, resulting in the reoccurence of
the bug in NixOS#22810, see
infinisil/all-hies#43
This commit fixes this by "unprettyfying" the package conf files before
processing them.

With this change I just pushed I can confirm that this fixes the issue |

Anybody have any objections? Otherwise I'd like to have this merged soon |

Seems to be failing, but that very much seems unrelated: I hope that's just a transient failure, I'll restart the build |

Nevermind, I can't restart that job, "Only the project members, administrators, and accounts with restart-jobs privileges can perform this operation." |

This commit fixes this by unprettifying the package conf files before
processing them. This also gets rid of a nasty sed expression previously used to do this conf format juggling
The only change of behavior is that whereas previously above line would be changed to
it now is changed to (
some-more-directoriesisn't present anymore)But this isn't a problem because all
.dylib's in those directories will have been symlinked into$out/lib/linksanyways.Ping @peti @copumpkin @Ericson2314 @LnL7 @shlevy
