Uh, clarification on my part: by "dynamic TclKit" I mean a binary that is
linked dynamically against the _system_ libraries (libc, libstdc++, etc).

The static TclKit distributed by equi4 is a statically linked binary, i.e.
ldd says "not a dynamic executable".

The distinction is pretty important in this case, as for the dynamic TclKit
there can be no conflict between the shared object code for libstdc++ as
loaded by TclKit, and libstdc++ as loaded by an extension.  OTOH if
libstdc++ is statically compiled into a binary and an extension dynamically
loads the system's shared libstdc++, nasty things happen.
