I fixed it with
<http://git.savannah.gnu.org/cgit/guile-reader.git/commit/?id=a572bd673026293e9bebb0237e1153d00e345348>
just recently.

Alternately, this can be worked around by running:

  LC_ALL=C make

If you configure with --with-guilemoduledir=/usr/share/guile/site/2.0 as
it suggests, you’ll be sure that the .scm files from Guile-Reader will
be found automatically; /usr/share/guile/site (the default) actually
works well too but has the disadvantage of being unversioned.

Indeed.  Fixed in commit 5fa1188.

This stems from the same problem as #1.

Thanks for the report!
