Bug report -- "Illegal instruction" on Mac 10.6.8 without XCode installed

Hi, I am running a Mac 10.6.8 and tried to install git-1.9.0 off of the installer (git-1.9.0-intel-universal-snow-leopard.dmg). The installation worked fine and gave no error messages. But whenever I type in a git command (see below for some I tried), it gives me this error message: Illegal instruction

I am completely new to git and mostly new of Unix, but here are some commands I tried: git git help git config git init git clean git config --global user.name "John Doe" git status

However, typing "man git" displays typical man pages. I do not have Xcode installed. (it's very hard to find a legacy copy); the "make" command also is not present, so I can't use any of the workarounds I saw listed. I uninstalled git-1.9.0 successfully using the provided script, then downloaded the same file again (and installed it) to make sure I didn't get a corrupt copy. I had the same problem, however. If I can provide any more information just let me know. Thanks for any help you can provide. -Ray
