getting started with the texlive importer

[Paul Garlick <pgarlick@tourbillion-technology.com>]

Hi Guix,

I have been trying to use the texlive importer to package some TeXLive
packages.

Using the example from the manual, I try:

$ guix import texlive fontspec

I get:

following redirection to `https://ctan.org/xml/1.2/pkg/fontspec'...
Backtrace:

So the 'svn export' command is causing an error.  Interestingly, if I
run the same command from the shell it succeeds; the files are
downloaded to the temporary directory.

Are others seeing the same thing?  I wonder whether a recent change in
guix has jiggered the importer.

Best regards,

Paul.
