Running rvm install ruby-1.9.3-p286 gives me this error:
Error running 'make -j 9', please read /Users/epeterson/.rvm/log/ruby-1.9.3-p286/make.log
There has been an error while running make. Halting the installation.

This took me forever to hunt down. Was trying different versions of make, gcc, etc.
It turns out the format of the rvm_make_flags environment variable has changed from a string to an array and was not well communicated or documented. This may apply to all rvm_* env variables, not sure.
Check your ~/.rvmrc and project/path/.rvmrc.
# before
export rvm_make_flags="-j 9"
# after
export rvm_make_flags=(-j 9)
After making this change everything compiled cleanly.

run rvm requirements and it would show all necessary components from RVM to work properly,
on my box, it shows(partial)
# For ruby:
brew install autoconf automake apple-gcc42 libtool pkg-config openssl readline libyaml sqlite libxml2 libxslt libksba
so I just run the command, and after than, issue
rvm install 1.9.3

I'm pretty new at this as well. I was not sure about the directions above, but I had a related problem.
What I found is that I just needed to restart Terminal.
I then used $ type rvm | head -1 and it spit out rvm is a function. Which is what you want to get according to the great article found here:
