[ERROR] Compiled without LIBSSH v0.4.x support, module is not available!
I downloaded LIBSSH from libssh.org and installed it to no avail. The internet seems to hold no answers however I can see others have asked the same question.
Thanks very much indeed, user.
I was having the same problem. I compiled and then realized I forgot libssh when I tried to run it against my router so I installed it and recompiled; still it was not working. I tried "make clean" and it worked like a charm.
