Hi Guillermo,

Thanks for the explanation.  I guess that I really don't have much idea how this baseline stuff is supposed to work, so when it fails, I don't know where to look.

My initial question was about why iceberg (or Metacello?) was looking in the wrong directory, but that seems to have been the wrong question.

So, you are right; the BaselineOfSmaCC has not been updated to include the SmaCC-Reification package, which is new (and experimental).  So it seems that I have to add it.  Here is the current baseline:

BaselineOfSmaCC >> baseline: spec

group: 'Tests'

with: #('SmaCC-Tests' 'SmaCC-Rewrite-Engine-Tests' 'SmaCC-Python-Tests') ]

Should I add a new group, something like

spec group: 'Reification'

with: #('SmaCC-Reification')

But then I must also specify the dependencies of the SmaCC-Reification package, so I need to add 

spec package: 'SmaCC-Reification' with: [ spec requires: #('SmaCC-Smalltalk-Parser' 'SmaCC-Runtime' 'SmaCC-Java') ]

(I assumed that this would go earlier in the method, with the other package specs.  So I put it right after package: 'SmaCC-IDL')

Once I've done that, I tried to load the BaselineOfSmaCC again, and I find that I've broken it.   I get a walkback with the message

"Could not resolve: SmaCC-Reification [SmaCC-Reification] in /Users/black/Development/Pharo/images/Pharo 7.0 SmallGrace 0.34/pharo-local/package-cache git@github.com:apblack/SmaCC.git[fglr]"

Why is it trying to load SmaCC-Reficiation?  Did my changes to the baseline somehow change the default configuration too?  

Moreover, my original problem is still there ��� it's looking in a nonexistent package cache, rather than on github, or in my ~/iceberg/apblack/SmaCC clone of github.

- If SmaCC-Reification is in a non-default group, you probably want to add 

spec

    baseline: 'SmaCC-Reification'

    with: [ spec repository: 'github://apblack/SmaCC:working'; loads: #( 'NAME-OF-YOUR-REIFICATION-GROUP' ) ].

This would go in the BaselineOfGrace package, right?   Not in BaselineOfSmaCC

And then your packages can depend on it.

- IF SmaCC-Reification is not in the SmaCC baseline, then, there is nothing you can do, but to add it :)

Thanks for the help so far
