In an attempt to build the OpenJDK tools with icepick, I'm getting an error when downloading the icepick tarball:
~~~~~~~~~~~~~ $ ./pre-inst-env guix download http://icedtea.wildebeest.org/hg/icepick/archive/15425b469aea.tar.gz starting download of `/tmp/guix-file.zrKNcT' from `http://icedtea.wildebeest.org/hg/icepick/archive/15425b469aea.tar.gz'...
