I want to have a version that does not include any dependencies on
ncurses, i.e. that stuff is not compiled in at all. 
It could be used for straightforward standard I/O, file filtering,
scripting, and even CGI programming.

The Euphoria interpreter, exu, is *much* smaller than Perl or Python.
I do not plan to spin off a separate shared library out of the backend.
It seems to me the O/S could detect that multiple exu's are running,
and only load one copy of the executable code for exu into memory.
