## This script requires OS 10.6 or later
#
## If you drag-install Xcode 4.3 or later, you must have opened Xcode 
## and clicked the Install button on the dialog which appears to 
## complete the Xcode installation before running this script.
#
## In Terminal, CD to the curl-7.47.1 directory.
##     cd [path]/curl-7.47.1/
## then run this script:
##     source [path]/buildcurl.sh [ -clean ]
##
## the -clean argument will force a full rebuild.
