I'm running into a bit of complication with code that is already loaded in GToolkit (but not Pharo) (e.g. XPath, XML-Parser, OSSubprocess) creating conflicts for users.

One option is to include an `#onConflict:` in the readme. However, this seems less than ideal because it doesn't cover being loaded as a dependency.

What I'm doing now is e.g.

```

spec

for: #( #GToolkit )

do: [

spec removeProject: 'OSSubprocess'.

spec

package: 'Tesseract' overrides: [

spec requires: (tesseractBaseDeps copyWithout: 'OSSubprocess') ] ]

```

However, it feels a bit like jumping through hoops. I'd rather add the requirement just on Pharo than remove it on GToolkit. The issue is that GT is a custom platform attribute.

So it occurred to me that one of two things would be helpful:

1. Make GToolkit a full-fledged platform (but not sure if there is a built in extension point for this

2. Say (pseudocode): `spec for: {{not GT}} do: ...`

Thoughts?

Sean,

You CAN define custom project attributes (see ConfigurationOf>>customProjectAttributes and [1]) ... implement #customAttributes in your BaselineOf and literally define #notGT based upon spelunking in the image at load time.
