[Etoys] trouble with etoys-dev.image and etoys.image

[polishookm]

I downloaded (today)

http://etoys.laptop.org/src/etoys-image-and-pr.zip

for use with SqueakLand.app (for OS X)

etoys-dev.image and etoys.image

appear to be actually etoys-dev.image

Trying to open a SqueakMap Package Loader (in etoys-dev.image) hangs Squeak.

Have I missed a direction somewhere ...?

Thanks in advance,

Mark
