#!/bin/bash
#
# This script builds all library dependencies of OpenSCAD for Mac OS X.
# The libraries will be build in 64-bit (and optionally 32-bit mode) mode
# and backwards compatible with 10.5 "Leopard".
# 
# This script must be run from the OpenSCAD source root directory
#
# Usage: macosx-build-dependencies.sh [-16lcdf] [<package>]
#  -3   Build using C++03 and libstdc++
#  -6   Build only 64-bit binaries
#  -l   Force use of LLVM compiler
#  -c   Force use of clang compiler
#  -d   Build for deployment (if not specified, e.g. Sparkle won't be built)
#  -f   Force build even if package is installed
#
# Prerequisites:
# - MacPorts: curl, cmake
#
# FIXME:
# o Verbose option
