Expected Results:

complete make install without error

to quote the README

to install the module run "make install" (you might have to be 'root' to have all necessary permissions to install the module).

If you note, it's not failing on permission, it's failing on lack of a crypto component, and I can't find any documentation from either ubuntu or here about what might be the appropriate fix.

i note that it is not failing at all (and that you didn't check other - closed - issues in this tracker, else you would have noted that others have had this "problem" before and that there really isn't a problem.
