Hi,

I released Guile-SSH 0.7.1 [1] in which some of the issues should be
fixed.  Namely the issue with failing `key.scm' tests should no longer
be seen.  But you do need a patch [2] to make libssh 0.6.3 work with
GCrypt, otherwise Guile-SSH `server-handle-key-exchange' procedure will
fail (and thus the tests that involve communication between a client and
a server will fail as well).

libssh 0.6.3 requires libgcrypt 1.5.0 or later.  I compiled libssh 0.6.3
with libgcrypt 1.5.4 and the patch applied; there are no test failures
seen with Guile-SSH 0.7.1 in this case.

Hope this helps.
