Environment: OS X 10.9 (Mavericks) and Xcode 5.0
Command line compilations/links fail with either:
"catastrophic error: cannot open source file "stdlib.h" OR with "ld: library not found for -lcrt1.10.6.o"
Affected compiler: Intel Composer XE 2013 Update 1
Root cause: Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications.
FIX: Install the Xcode 5.0 "Command Line Tools". Follow this Knowledge Base article for installation of this package: http://software.intel.com/en-us/articles/installing-intel-compilers-for-os-x-pre-requisite-xcode-command-line-tools
