RVM expects a specific port to work around ruby certificate issues, but I don't want to use that port (certsync provides the same certificate DB but uses my Mac's certstore instead).
There's a couple way I would propose solving this:
I worked around this issue for now by installing the packages I need, then switching autolibs to read-only:
[bhatfield@twitmac ~]$ rvm reinstall ruby-2.1.1
ruby-2.1.1 - #removing src - please wait
ruby-2.1.1 - #removing rubies - please wait
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.9/x86_64/ruby-2.1.1.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Missing required packages: curl-ca-bundle
Certificates in '/opt/local/etc/openssl/cert.pem' already are up to date.
Requirements installation successful.
As you can see, even with the missing required package, the certificate validation step passes.
