I am now turning to Pharo... and I managed to get Pharo 3.0 and 6.1 to 
load what I can load in Gemstone3.4 with/without a network connection, 
BUT... I now have issues loading our own project. Our own project is 
loaded via a BaselineOf which only contains internal packages on the 
local filetree repo.

It breaks with a 'Apparent loop in before/after dependency definitions' 
while trying to do 
MetacelloMCVersionSpec(MetacelloVersionSpec)>>packageSpecsInLoadOrder

I have put the (very short transcript) and stack from Pharo6.1 on 
pastebin [1]. The MetacelloPackagesSpec asString is also useful - but it 
contains information I'd rather keep confidential, so I will email that 
off-list.  (I have also pushed the dependencies as per the output of 
that MetacelloPackagesSpec asString through a topological sort and found 
no circularity.)

Can you shed any light?
