Update the references to the file "LICENCE" with "COPYING". The file LICENCE doesn't exist in ruby/ruby nor ruby/openssl. This has been always the case since OpenSSL for Ruby 2 was merged to the ruby tree as a standard library in 2003. In OpenSSL for Ruby 2's CVS repository[1], the LICENCE file contained an old version of the Ruby License, identical to the COPYING file that was in Ruby's tree at that time (r4128[2]). [1] http://cvs.savannah.gnu.org/viewvc/rubypki/ossl2/LICENCE?revision=1.1.1.1&view=markup [2]231247c010/COPYING5bccf07d04
