在OS X Mountain Lion上通过RVM安装Ruby时运行’make’时出错

这是我第一次使用 Ruby.我意识到不要使用sudo来安装Gems,所以我按照这个tutotrial( http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac)来安装RVM,以便我可以更新我的Ruby版本,然后安装Middleman( http://middlemanapp.com/).

RVM安装工作,但在’#compiling’阶段安装Ruby 1.9.3时,我收到以下错误：

Error running ‘make’,please read
/Users/Mark/.rvm/log/ruby-1.9.3-p385/make.log There has been an error
while running make. Halting the installation.

我打开了日志文件,与我见过的许多其他问题不同,该文件不包含对’readline’的引用,而是’compile’,我认为它与Ruby安装的’#compiling’阶段有关.以下是make.log的输出：

如果我运行’make –version’,我会得到以下输出：

我很难找到一个完全匹配的问题,所以如果有人能提供帮助那就太棒了.

干杯,
