Oops, sorry. Here's the contents of the file rather than attaching it.

# This script performs all of the steps needed to build a 32 bit
# universal binary libcurl.framework for Mac OS X 10.4 or greater.

VERSION=`/usr/bin/sed -ne 's/^#define LIBCURL_VERSION "\(.*\)"/\1/p'



ARCHES='-arch ppc -arch i386'

# Use these values instead to produce a 64 bit framework that only
works on 10.5.
# You can't currently build a combined 32/64 framework.
