I get the following error when trying to RVM install 1.8.7-p302:

 shawn-taylors-macbook-pro-2:~ shawntaylorphoto$ rvm install 1.8.7-p302

...

 ERROR: Error running ' ./configure
--prefix=/Users/shawntaylorphoto/.rvm/rubies/ruby-1.8.7-p302

/Users/shawntaylorphoto/.rvm/log/ruby-1.8.7-p302/configure.log ERROR:
There has been an error while running configure. Halting the
installation

I checked the configure.log file as suggested, and get this:

details.

Is Xcode an acceptable C Compiler? I would think so. I've got it in /Developer, but not in ~/Users/username/... Thinking this is the problem, and if so, can I tell RVM to look there for the C compiler, or is it better to install Xcode in the /user folder?

Alternately, if I'm totally off and neither of these is the problem and solution, any other advice would be hugely appreciated!!!

As per the Tin Man's instructions, here is

Add the output of rvm info to your question by editing it. – the Tin Man
What's the output of which gcc. So you did not install Xcode in /Developer like it defaults to? – Dylan Markow
Thank Tin man - done that now. – Shawn Taylor
Dylan, it is in the /Developer folder - I just described that wrong. Have corrected it now:) – Shawn Taylor

You will need to install the "Developer Tools" sub-system which is on your OS X install disc.

I suspect XCode needs to be in its default installation location. On all my Macs that has been in /Developer.

Also, you don't say what version of the OS you are running, but there are buggy versions of XCode so it helps to have the most current version for your OS.
