From: "Dr. Hegewald" Date: 2013-02-27T18:32:24+09:00 Subject: Mac OS 10.8.2 and openssl Hi everybody, I just installed the current ruby 2.0.0p0 on a Mac OS 10.8.2. $ ruby --version ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.2.0] Then I want to install my gems as usual: $ gem install terminal-notifier ERROR: Loading command: install (LoadError) cannot load such file -- openssl ERROR: While executing gem ... (NoMethodError) undefined method `invoke_with_build_args' for nil:NilClass I remember reading that ruby 2.0 is not using the SSL gem anymore, but the system installed openssl instead. I guess this is the problem here, but there is an openssl available in my $PATH: $ which openssl /usr/bin/openssl I guess this is an FAQ, but could not find anything related. What is the prefereed way to fix this? Do I have to explicitly tell ruby where the openssl lives? Many TIA, Jan Hegewald
