Fedora 15下将Rails程序部署到Heroku

Question

[root@chris-notebook helloworld]# heroku create helloworld --stack cedar
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- readline (LoadError)

    from /usr/local/bin/heroku:19:in `<main>'

当我尝试创建它时，每次都会遇到同样的错误。 我应该怎么办？我在 Ubuntu 下看到了类似的问题。他们通过去某个地方 ...src/ruby../ext/readline 然后执行来解决它，

ruby extconf.rb
make
make install

但我在文件系统中没有看到该文件夹​​。为什么这一切如此困难？

更新

通过安装下一个软件包解决

readline-devel.i686
readline-static.i686

，然后在放置在下载的 ruby​​ 源中的文件夹 ext/readline 中进行类似的操作。
