Thanks, that's nice to hear !

The library is not well-document as you know.
The fact that the ngram order defaults to 3 is documented in the 
ngram-count man page.
I certainly don't want to make any claims for the quality of the documentation
in general.

BTW, if anyone feels like improving the document (fixing or expanding it)
I'd be more than happy to accept submissions ...

I would recommend just disabling the Tcl stuff ti avoid the problem.
It's not important enough to track down this dynamic linker issue.
