Max,

Where are you getting that package from?

I just checked and the version available from GemSource[1] loads 
(unzips) in both GemStone/GsDevKit and Pharo3.0...it's almost certain 
that the Metacello and that package has been tested against Squeak4.5 
and a couple of earlier versions as I've just run a test against the 
latest Metacello up on Travis .. I am not testing against Squeak4.6 ... 
yet ... but I have been testing regularly against the Squeak-Trunk and 
those tests passed today[3][4]

So perhaps the problem with the mcz file is in how Squeak 4.6 unzips things?

I suppose I should add Squeak4.6 to my Metacello lineup, but I've been 
waiting for a PR from Frank[2] and it looks like he is waiting for the 
Squeak 4.6 release.
