Error updating my version of Ruby using RVM on Mac OS X 10.6.6

Question

I tried updating Ruby on my Mac OS X 10.6.6 system. Now I have 1.8.7, and I want to upgrade to 1.9.2. When I typed rvm install 1.9.2, I received:

gal-harths-iMac:~ galharth$ rvm install 1.9.2
/Users/galharth/.rvm/rubies/ruby-1.9.2-p136, this may take a while depending on your cpu(s)...

ruby-1.9.2-p136 - #fetching 
ruby-1.9.2-p136 - #extracted to /Users/galharth/.rvm/src/ruby-1.9.2-p136 (already extracted)
ruby-1.9.2-p136 - #configuring 
Error running ' ./configure --prefix=/Users/galharth/.rvm/rubies/ruby-1.9.2-p136 --enable-shared  ', please read /Users/galharth/.rvm/log/ruby-1.9.2-p136/configure.log
There has been an error while running configure. Halting the installation.

I installed Xcode and it still does not work.

This is the configure.log file:

Answer 3

, Snow Leopard, Xcode. C, . : http://www.brianp.net/2009/09/05/snow-leopards-ate-my-c-compiler/

In my case, as soon as I solved the problem with the compiler, I got a permission error. Running as root in bash gave rvm the appropriate permissions.

If you use Lion verification, make sure you have the command line tools installed. They separated them from Xcode, so now they are a separate download. You can find them here:
