Emacs.app & carbon emacs

[Brian Flaherty]

Hello,

I have Emacs.app installed, and I'd like to install emacs +carbon
too.  When I did that, everything was fine until activation:

--->  Activating emacs 22.2_0+carbon
Error: Target org.macports.activate returned: Image error:
/Applications/MacPorts/Emacs.app/Contents/Info.plist is being used by
the active emacs-app port.  Please deactivate this port first, or use
the -f flag to force the activation.
Error: Status 1 encountered during processing.

What does it mean to force it?  Will they peacefully coexist?

Thank you for your time.

Brian
