Scripting within GNUstep

Hello,

As we previously discussed about the openURL service and filter, I was 
trying to create one with scripting.

The StepTalk framework is installed, but seemingly with an incomplete 
or limited Smalltalk compatibility.

Only a basic Hello World! seems to work:
	Transcript show: 'Hello World!\n'

When I try some other commands, e.g.:
	'Hello' indexOf: $e

I receive such an error message:

stexec: Uncaught exception STInternalInconsistencyException, reason: 
No method signature for selector 'indexOf:' for receiver of type 
GSMutableString

There are my two questions:

- Do we need to install a complete Smalltalk runtime to use StepTalk 
within GNUstep?
- Is the StepTalk Framework limited with GNU runtime?

Regards,
