Hello Igor!

Thank you for the patch, it has helped and now it looks like the Alien
is loaded... But.

When I'm sending an #asAlien message to a simple string, e.g.

'xmessage something' asAlien

The executions fails with the primitiveFailed exception here:
Alien >> sizeFieldPut: size "<Integer> ^<Integer>"
	<primitive: 'primSizeFieldPut' error: errorCode module: 'IA32ABI'>
	^self primitiveFailed

I assume that the Alien-Core package was not loaded properly. What am
I doing wrong?
