Yeah, thanks, that seems to be the case. Actually, "luflac-x" is the name of the channel, and its derivation fails to build. Apparently, the problem is in a custom guile build system I defined in the channel. If I remove the build system and the packages that depend on it, the channel builds again. So I have to inspect that. Unfortunately, though, the errors related to using a local URI as the URL of the channel still remain, even if I remove the custom build system and the packages that depend on it. > Sorry I cannot be more helpful. No problem, thanks for taking a look :)
