See 3be4b61aa4 (Link with -lcrypto instead of -lssl when using openssl libraries., 2005-05-10). I also needed -lz. See 9426167765 (Add "-lz" to link line to get in zlib., 2005-04-08). You can patch the Makefile, or just override it like: make LIBS='-lcrypto -lz' which builds for me on current Debian unstable. I don't think you can actually fetch with that old build, but I used periodically check that Git v1.0 can fetch happily from GitHub. I haven't in a while, so let me know if you try it and it doesn't work. ;) -Peff
