Question

我正在使用以下内容编译自己的Web服务器：

卷曲7.43.0
的httpd-2.4.12
jpegsrc.v9
的libpng-1.6.18
libxml2-2.9.2
PCRE-8.37
PHP-43年4月5日

我在MacOS 10.9上没有问题，但我在MacOS 10.8上遇到此错误：

httpd: Syntax error on line 18 of /Webserver/httpd-2.4.12/conf/httpd.conf:  
Cannot load modules/libphp5.so into server: dlopen(/Webserver/httpd/modules/libphp5.so,10): Symbol not found:___exp10  
  Referenced from: /Webserver/libxml2-2.9.2/lib/libxml2.2.dylib  
  Expected in: /usr/lib/libSystem.B.dylib  
in /Webserver/libxml2-2.9.2/lib/libxml2.2.dylib

我想知道如何调试这个？
我已经使用otool -L，但我必须承认我不知道如何解释结果：

> otool -L /Webserver/httpd/modules/libphp5.so

我可以使用哪些工具？
