由于系统升级到了mac os x 10.7.4，xcode目录也变到了/Applications/Xcode.app，所以要编译iphone版的就要做些修改，找到build/config/iPhone文件打开编辑，修改如下：
IPHONE_SDK_VERSION = 5.1
GCC_VER = 4.2
IPHONE_SDK ?= iPhoneOS
IPHONE_SDK_ROOT = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
POCO_TARGET_OSARCH ?= armv7
TOOL_PREFIX ?= /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/
make
make install
