i recently moved to snow leopard and had to reinstall macports and a newer version of xcode now im to install git but got this error twice already. I'm sort of unexperienced and can't make what the log is compalining about which i attach below. Thanks!

Looks like libz was installed under your previous OS and MacPorts install.
