I might add the following footnote: When Openmcl.app is launched, its 
name in the menu bar is OpenMCL, but its name in the dock is dppccl. 
This is because the executable running is dppccl.

If you make OpenMCL standalone and rename 
OpenMCL.app/Contents/MacOS/dppccl to 
OpenMCL.app/Contents/MacOS/OpenMCL, then OpenMCL's name in the Dock 
will match its name in the menu bar (i.e., "OpenMCL"). However, if you 
then try to execute (require 'cocoa) or try to load 
ccl/examples/cocoa.lisp, OpenMCL will die with:
RegisterProcess failed (error = -50)
I don't believe that this was the case under Jaguar, but I may be 
misremembering. It clearly is the case under Panther, however.

Changing the name back to dppccl fixes this problem. If you want the 
Dock name and menu bar name to match, you can make a separate copy of 
OpenMCL.app with dppccl renamed to OpenMCL, and place it somewhere 
other than the ccl directory, such as /Applications. This however, 
leads to another problem - failure of certain files to autoload when 
needed since openmcl is looking for them in a relative directory which 
isn't there.

I'm sure there would be other ways to fix this minor inconsistency, but 
I'm equally sure that Gary and Randall would have more definitive fixes 
than I might cook up.
