I'm working off a relatively clean OS X install. I had Xcode, but removed it. 

When I type `rvm install 1.9.3`, I get:

```

curl performs SSL certificate verification by default, using a "bundle"  of Certificate Authority (CA) public keys (CA certs). If the default  bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in  the bundle, the certificate verification probably failed due to a  problem with the certificate (it might be expired, or the name might  not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use  the -k (or --insecure) option. There was an error, please check /Users/max/.rvm/log//*.log. Next we'll try to fetch via http. Trying ftp:// URL instead.   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Weird things seems to be happening, like I don't have a default system. This is the first time I've tried installing Ruby (eventually trying to get to Rails), so this whole process is quite foreign to me. 

I've checked a couple of the logs the output mentions and most of the time RVM is looking for a file that doesnt exist (however it says it was downloaded) or a program that doesnt exist (it was trying to run `./configure` and got a "File not Found").

Can anyone shed any insight on this? I want to get my hands dirty with Rails ASAP.
