I caved and installed gcc 4.7 in /usr/local/ and a pre-compiled openssl-1.0.0g
pkg in /usr/local/ssl. I got the following error, when compiling
squid-3.2.0.16-20120316-r11543 on OS X 10.7.3. Is this something that can be
worked around without removing -Werror from Makefile(s)?
export CPPFLAGS="-I/usr/local/ssl/include"
export CFLAGS="-I/usr/local/ssl/include"
export LDFLAGS="-L/usr/local/ssl/lib"
export LIBS="-ldl"
