The libssh2 library is required by this module.  If you don't have it, you can
download it from http://www.libssh2.org; you may also need OpenSSL, which can be
obtained from http://www.openssl.org.

Debian:   sudo aptitude install libssh2-1-dev
OpenSUSE: sudo zypper in libssh2-1 libssh2-devel

You can pass your libssh2 lib and include dirs on the command line. E.g.:

    perl Makefile.PL lib=$HOME/libssh2/lib inc=$HOME/libssh2/include

Can't link/include 'libssh2.h', 'ssh2'
No 'Makefile' created  RKITOVER/Net-SSH2-0.39.tar.gz
