Failing to build some packages

[Lukas Gradl]

Hello!

Since early this week I seem to be unable to build some packages in
master.  I am not sure what the problem is, I think I am working with
a clean copy of origin/master, so I doubt that any of my own hacking
broke anything.  Here is what I see:

Does anyone else have this problem or a way to fix it?  I see this for
several other packages as well.  I thought maybe my store is corrupt, so
I did 'guix gc', but the problem persisted.

I don't quite understand the code that throws this error and I have
absolutely no idea what is going wrong here.


Thanks in advance for your help!

Best,
Lukas
