ConfigurationOf* are not obsolete. You see the emphasis on BaselineOf, 
because I think that git/github is superior to Monticello files for 
multi-developer open source projects. When a project is stored in a git 
repository it is not necessary to record the versions of the individual 
mcz files in the ConfigurationOf* (a very tedious process) so the 
"version specs" aren't necessary.

It is still necessary to specify the package and project dependencies so 
the BaselineOf was invented to specify only the package/project 
dependencies....

tODE has been specifically designed to support a development model based 
on git and github and I am in the process of converting all of the 
projects used by GLASS/GsDevKit to GitHub and BaselineOf*.

ConfigurationOf* will continue to be supported "forever" however, I want 
to encourage folks to move their projects to git, because the ecosystem 
around git-based repositories continue to be improved.

For Seaside 3.0 I think that you can only use ConfigurationOf* ... there 
are ways to create tODE project entires for ConfigurationOf* 
projects[1], but I think that for ConfigurationOf* development you 
should continue to use Metacello load expressions and custom Smalltalk 
expressions. I would suggest that you create tODE scripts using `touch 
sh <script-name>` for your load scripts and other maintenance tasks. Ask 
questions on this list if you need some more pointers.

This error sees to be a case where the stone may not have been setup 
correctly ... tODE expect there to be a "standard directory structure in 
well known places" and this error seems to indicate that perhaps there 
is a problem in this area ... could you give me more details about how 
you "managed to (mostly) install tODE" because perhaps you are hitting 
errors because of the "(mostly)" bits ...

You can get a stack from a command error using `debugMode --set` (see 
`debugMode -h` for more details) and the stack will help me track down 
what is wrong ..

These are all things that work when stones are created using the 
GsDevKit_home `createStone` command, so I am wondering where you might 
have departed from the standard installation ... "managed to (mostly) 
install tODE"  makes me wonder ...
