Ok. That file contains a line that reads:

]style[(6 41 26 95 56 16 27 17
257)bcblack;,cblack;,f0,cblack;,f0cblack;,f0,f0cblack;,f0,f0cblack;!

This is the Squeak syntax for embedding text styles in code. Cuis does not
support this. If I remove this line and try again, I get a compilation
error from OMeta2Compiler... This is in your side now.

I'm willing to help, but I'm not learning about OMeta, at least not now.
So, what I need to be able to further help you is report like "on input
xxxx, Squeak compiler has behavior yyyy that is ok, and Cuis has behavior
zzzz that is wrong" or something like that.

Cheers,
