Bloodrayne: Applescript error = sh: gzip: command not found (127)

[mrpatrickb]

I'm trying to install Bloodrayne and when the installer runs, I get the error:
Applescript error = sh: gzip: command not found (127)

I've tried 3 separate machine: one with leopard, one with panther and one with the games requirement of 10.2.
Get the error each time.

How do I fix this?

I manually unpacked everything and put all the extras in the resource file and now it works.

But incase I missed something, who else plays this and know about the above error? or can share the file folder placement with me so i know I moved everything to the right folders (so no future bug comes up)
Thanks
