unable to build livecode externals for ios7.1 on xcode5.1.1

[RajaRamesh]

Dear forum members,
Iam trying to build rremicrophone and rrehardcopy externals for ios 7.1 , but iam getting following 3 errors.

Users/ensis/Library/Application Support/RunRev/Components/LiveCodeSDK/tools/lclink.sh: line 34: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++: No such file or directory
error: linking step of external dylib build failed, probably due to missing framework or library references - check the contents of the rremicrophone.ios file
Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure

can any one please guide me to resolve this issues or please build and give me the rremicrophone and rrehardcopy lcext files for ios7.1, iam going to use this lcext for ipad, with LC 6.6.2 stable version.
please help me.
