That a package (well, derivation) upon which rust@1.30.1 depends 
failed to build.

I'm almost certain that Cuirass doesn't currently track dependency 
information the way it eventually should, which would mean there's 
no way to find out *which* dependency failed.  The only way to 
find out would be build rust@1.30.1 yourself and see what fails 
before you get to it.  If you do get to it, you managed to build 
something that ci.guix didn't and you should feel proud.

I logged into my substitute server to find out more, but:

  /gnu/store/p20fkgdlqqw4dlfqg8jximqg6qpcz7a1-rust-1.30.1

Looks like I already built the entire rust chain successfully. (?)

You're welcome to give my substitute server at https://guix.<my 
domain name> a try (more info at that URL).  I'd be interested in 
both success and failure.  :-)

Edit the package definition to add ‘#:tests? #f’ to the arguments 
field.  This will change the derivation and all that depend on it 
(so you won't get substitutes for anything that depends on your 
untested rust fork).

Kind regards,
