In the "Squeak-4.6-All-in-One.app" I can see the same problem on Microsoft Windows:

First it is necessary to change/update:

gemsource

        ^ self monticello http: 'http://seaside.gemtalksystems.com/ss'

This by itself is already extremely suspicious, as it shows that the Squeak4.6
image has an incorrect URL for gemstone (gemsource).

Next:

"Load the Preview version of Metacello from GitHub"
(Smalltalk at: #Metacello) new
  configuration: 'MetacelloPreview';
  version: #stable;
  repository: 'github://Metacello/metacello:configuration';
  load.

results also on Microsoft Windows in :

Could not resolve: ConfigurationOfMetacelloPreview [ConfigurationOfMetacelloPreview] in C:\Users\stes\squeak\Squeak-4.6-All-in-One\Squeak-4.6-All-in-One\Squeak-4.6-All-in-One.app\Contents\Resources\package-cache github://Metacello/metacello:configuration ERROR: 'GoferRepositoryError: can''t find EOCD position'

This is with the following VM:

So basically it seems the current Metacello *CAN* be used with Squeak4.6,
but there are some issues with it.

Perhaps an older Metacello should be used with Squeak 4.6 ...

However the instructions at 

https://github.com/Metacello/metacello#squeak-older-than-squeak52

seem to imply that it should work on "older than Squeak 5.2",
unless the Metacello authors mean by that on Squeak 5.0 and 5.1
(excluding older than 5.0 for example).
