How to get RVM + Subversion Ruby Bindings to work

OS X Snow Leopard

$ rvm use 1.8.7-p302
$ wget http://subversion.tigris.org/downloads/subversion-1.6.15.tar.gz
$ tar -xzf subversion-1.6.15.tar.gz && cd subversion-1.6.15
$ ./configure --with-ruby-sitedir=~/.rvm/rubies/ruby-1.8.7-p302/lib/ruby --without-berkeley-db
$ make swig-rb && make install-swig-rb

To test things out:
$ irb
ruby-1.8.7-p302 > require 'svn/client'
=> true
ruby-1.8.7-p302 > exit

Ubuntu 10.10

To install RVM:
$ sudo apt-get install build-essential curl git-core ruby
$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session' >> ~/.profile
$ source ~/.profile
$ rvm package install readline
$ rvm package install zlib
$ rvm install 1.8.7 --with-zlib-dir=/home/you/.rvm/usr --with-readline-dir=/home/you/.rvm/usr
$ rvm --default 1.8.7

Now the bindings
$ sudo apt-get install libsvn-ruby
$ cd /usr/lib/ruby/1.8
$ cp -R svn /home/you/.rvm/rubies/default/lib/ruby/1.8
$ cp -R x86_64-linux/svn /home/you/.rvm/rubies/default/lib/ruby/1.8/x86_64-linux/

To test things out:
$ irb
ruby-1.8.7-p330 :001 > require 'svn/client'
 => true 
ruby-1.8.7-p330 :002 > exit

I found this command worked for me on OS X Lion:

env CC=gcc-4.2 LDFLAGS="-L$MY_RUBY_HOME/lib" ./configure --with-ruby-sitedir=$MY_RUBY_HOME/lib/ruby --without-berkeley-db

Thanks mate, you saved my day!
