# How to Install RVM, Ruby, and Gems without Xcode Command Line Tools
# ===================================================================
#
# Mac OS X 10.8.2 (12C60) (Mountain Lion)
# Xcode 4.5 (4G182)
#
# While attempting to `rvm pkg install openssl`, I had encountered the error:
# > cryptlib.h:62:20: error: stdlib.h: No such file or directory
# But, the commands & ouput below show how I worked around the issue.
#
# Note: I replaced all occurrences below of my home directory path (/Users/username) with ~
#
# UPDATE: I never got this working. Use Homebrew to install Ruby without Xcode Command Line Tools. It works great!
