# If you're having cert issues on ruby 2.0.0-p0, the issue is most likely that ruby can't
# find the required intermediate certificates. If you built it via rbenv/ruby-build, then
# the certs are already on your system, just not where ruby expects them to be.

# When ruby-build installs openssl, it installs the CA certs here:
~/.rbenv/versions/2.0.0-p0/openssl/ssl/cacert.pem

# Ruby is expecting them here:
$(ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE')
# Which for me, is this path:
~/.rbenv/versions/2.0.0-p0/openssl/ssl/cert.pem

# So to fix the problem, all I had to do was this:
(cd ~/.rbenv/versions/2.0.0-p0/openssl/ssl && ln -s cacert.pem cert.pem)

# Woohoo!
