我尝试在 Snow Leo 上安装 ruby-ldap，但失败了：

~/WorkingFolder/temp/test$ sudo gem install ruby-ldap
Password:
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-ldap:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more

use the option '--with-ldap-dir'!


Gem files will remain installed in /opt/local/lib/ruby/gems/1.8/gems/ruby-ldap-0.9.11 for inspection.
Results logged to /opt/local/lib/ruby/gems/1.8/gems/ruby-ldap-0.9.11/gem_make.out

谁知道怎么解决这个问题，请帮忙！！

谢谢

【解决方案1】：

LDAP 开发标头在您的系统上不可用，而 ruby-ldap 需要这些标头。安装 Apple 的开发工具 (XCode) 也应该安装这些开发头文件。你能安装开发工具并重试安装 ruby-ldap 吗？
