如何安装Nokogiri作为Macruby宝石？

Question

最新的MacRuby发行说明(版本0.6)指出，作者已经设法使该版本与SQLite和Nokogiri一起工作。然而，当我运行sudo macgem install nokogiri时，我会得到以下错误：

ERROR:  Error installing nokogiri:

extconf失败：

然后是一系列的路径，然后是：

libxml2 is missing.  try 'port install libxml2' or 'yum install libxml2'
/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/Gems/1.9.0/gems/nokogiri-1.4.1/ext/nokogiri/extconf.rb:1:in `<main>': libxml2 is missing.  try 'port install libxml2' or 'yum install libxml2' (SystemExit)

有人知道怎么做吗？我的平台是MacOSX10.6.3。Nokogiri通常(指普通的老红宝石1.8.7)安装时没有问题。

进展

好吧，我有：

1. git clone http://github.com/tenderlove/nokogiri.git
2. cd nokogiri/ext/nokogiri
3. Then我已经用sudo port upgrade --enforce-variants libxml2 +universal和sudo port upgrade --enforce-variants libxslt +universal
4. Then重新构建了宏端口库，我执行了macruby extconf.rb successfully
5. Then，然后继续到make

此时，它出现了如下错误：

Answer 1

我认为您必须从源代码构建，因为只有Nokogiri的头是符合MacRuby的

我上传到GitHub，我做了一个包。http://wiki.github.com/Watson1978/nokogiri-macruby/
