The doc on the wiki says 0.5.0 is the minimum version of libssh.
The debian package (file debian/control) says 0.6.0 is the minimum

Which one is correct?
(the RPM PR was copied after debian package and currently checks for 0.6.0 as minimum as well)

(0.6.0 exclude older distros such as CentOS 6 and Ubuntu 12.04)
