Andreas,
Here's the Transcript from a (successful) load of WebClient:
Loading 1.0 of ConfigurationOfWebClient...
Fetched -> ConfigurationOfHelpSystem-tbn.12
Loaded -> ConfigurationOfHelpSystem-tbn.12
Fetched -> WebClient-Core-ar.15

Project: HelpSystem
Fetched -> HelpSystem-Core-tbn.40
Fetched -> HelpSystem-Tests-tbn.9
Fetched -> Pharo-Project-Help-tbn.8
Fetched -> WebClient-Help-ar.4
Fetched -> WebClient-Pharo-ar.1

In your configuration you had specified that WebClient-Help required the Help
System, so you can see that the load of the Help System was inserted at that
point in the load (which is what triggered the bug, too).
The order of specifying packages/projects implies the order that things will be
loaded in. With #requires:, the load order is explicit.
I would recommend that you explicitly use #requires: unless only one or two
packages are involved.
The implicit load order is not obvious when you introduce conditional loading
(with #squeakCommon #squeak, and #pharo), so if load order matters I would
explicitly declare the relationships.
The other aspect besides load order is what you want loaded. By default all
packages/projects are loaded, but you can define a 'default' group which would
be used to specify a subset of the packages/projects that are loaded by
default. This is useful if you want to control whether or not a set of packages
(say tests) are loaded or not ...
I don't think I've completely answered your questions so we might want to
continue the dialog on this question....
