Linking fails without zlib

[barracuda156]

Not sure how this was supposed to work, since nothing in the build passes -lz, but linking fails without it with a lot of undefined symbols like _uncompress, all of which sit in zlib.
Adding /opt/local/lib/libz.a (assuming MacPorts paths and preference for static linking) to this

gsocket/configure.ac

Line 144 in a814261

LDADD_STATIC="${STATIC_LIBSSLDIR}/libssl.a ${STATIC_LIBSSLDIR}/libcrypto.a"

line fixes the error.
