Hi Guix!

the Guix TeX Live importer is broken for me:

I tried running the SVN command that throwed (I tried to guess it from
the error log) and it ran successfully:

So I would guess the problem would be to the inputs to the build
environment that 'guix import texlive' is using, but I didn't dive into
the source code.

I picked the fontspec package because it is the example used in the
manual for the TeX Live importer, but it failed for me with other
packages too.

Any thoughts on this?


Thanks,
EuAndreh :)
