I's really a plugin, and it's intended to be loaded into Tcl shell of
any version (8.4, 8.5, 8.6), so linking to a specific Tcl library
isn't desirable. On the other hand, tclreadline uses so called stubs
where all public Tcl functions are stored in a big table of pointers
(see struct TclStubs and macro definition of Tcl_Eval in
/usr/include/tcl8.5/tclDecls.h), so it is seems to be a bug if
Tcl_Eval is called directly.

I'll see what can be done to fix it (and the linking as well).

Cheers!
