What version of the product are you using? On what operating system?

OS-I'm using OS X 10.5.7
scons-v1.2.0.r3842

Please provide any additional information below.

I'm using a 15" MacBook Pro that's only a few days old.(I don't know if that's relevant)

Any addition information you need just ask. Please help.

Thanks in advance.
