I'm running the command above trying to install git-core and I don't understand what the log is telling me.

Please remember to use WikiFormatting when writing in Trac.

The log appears to be telling you that the sed and expr commands cannot be found. These are standard UNIX commands that are part of every OS X install; if they're missing on your system, other commands may be missing as well, and the simplest way to get them back would be to reinstall OS X.
