我刚刚安装了 Ruby EE 11.01。我有一个 Rails 2.3.8 应用程序在 Apache2 上针对乘客 3.0.2 运行。现在，我的应用程序不会出现。错误是：
no such file to load -- iconv
我在 Mac OS X 10.6.4 上。我安装了 Ruby EE：
sudo ./installer -c --with-openssl-dir=/opt/local -c --with-readline-dir=/opt/local -c --with-iconv-dir=/opt/local
“哪个iconv”产生：
/opt/local/bin/iconv
尝试安装 gem iconv 会产生：
Building native extensions. This could take a while...
ERROR: Error installing iconv:
ERROR: Failed to build gem native extension.
/opt/ruby-enterprise-1.8.7-2011.01/bin/ruby extconf.rb

checking for iconv() in -liconv... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
我的 iconv 路径在安装行中是否错误？帮助！
编辑：
查看上面的日志文件，我看到了这一点：
