Hello, I'm trying to install Ruby 1.9.1 alongside 1.8.7 on Snow Leopard. I'm following the instructions here http://blog.twg.ca/2009/09/livin-on-the-edge-ruby-rails-and-snow-leopard/ but here's where it's failing: MacBookPro:~ martine$ rvm install 1.9.1 <i> Installing Ruby from source to: /Users/martine/.rvm/ruby-1.9.1-p376 </i> <i> Extracting ruby-1.9.1-p376 ... </i> <i> Configuring ruby-1.9.1-p376, this may take a while depending on your cpu(s)... </i> <e> Error running './configure --prefix=/Users/martine/.rvm/ruby-1.9.1-p376 --enable_shared ', please check /Users/martine/.rvm/log/ruby-1.9.1-p376/configure.error.log </e> and the log shows: [2009-12-14 18:41:52] ./configure --prefix=/Users/martine/.rvm/ruby-1.9.1-p376 --enable_shared configure: error: unrecognized option: `--enable_shared' Try `./configure --help' for more information. Any ideas? Thanks in advance! -- Posted via http://www.ruby-forum.com/.
