I am on OS X 10.9.4.

Note that Monticello is not actually dirty, and Environments is dirty because it has two ancestors, nice.47 & cmm.51 (as you report below).  You can find the script here:

I just tried your script in a Squeak4.5-13680.image starting with an empty package-cache. That is the image you use, if I interpret http://www.squeakvm.org/svn/squeak/branches/Cog/image/envvars.sh correctly, right?

It results in "Error: Bits size mismatch" when trying to add Morphic-cmm.730.mcz to the cache. Does it currently work for you?

Cheers,
Bernhard
