It=E2=80=99s just the Guile tarball that fails to be downloaded, because
build-aux/download.scm is simple-minded and only tries one URL, which is
alpha.gnu.org.

So you can either temporarily modify build-aux/download.scm to point to
fdn.fr/..., or download the file in question by hand and check its hash
against the one that=E2=80=99s in Makefile.am.

N64 seems to be appealing, at least for bignum-consuming apps.  The
binaries Nikita provided appear to be N32, which may mean they can only
be used to built N32 binaries?

Thanks,
