Root Root Backflip on Mac

[Squewheet]

I've been trying to root my motorola backflip 1.5 on my mac. It's a 27" intel iMac. And I've read a tutorial and i've downloaded the sdk tools and everything but the problem i'm having is. After I type the following below

cd ~/
touch .bash_profile
open -e .bash_profile

export PATH=${PATH}:/AndroidSDK/tools

is says to type in the terminal window the following below

. .bashrc

but when I do I get the following below.

-bash: .bashrc: No such file or directory

Can anyone tell me what is going wrong here. I've tryed to ask at the other sites that have the tutorial but it seems everybody is not there or no one visits those sites anymore. All help is appreciated!

Thanks
Squewheet

Does anyone know how I can root my backflip on my mac. I know there has to be other ways without using a pc.
