 In case things don't workout here follows a small cookbook to get
 things to work under different circumstances:

+TCL issues:
+===========
+On FreeBSD 3.2 and later which are ELF-based, tclsh (up to and including
+8.2.0) and wish should be linked with the -rdynamic gcc option (or
+equivalently -Wl,-export-dynamic, or -export-dynamic for ld). The
+standard TCL Makefiles don't do it. This will preclude any kind of
+dynamic loading because Tcl_PkgProvide() will be undefined when trying 
+to load the module. -rdynamic should probably be used on all ELF-based 
+systems (it is used on Linux already).
+
+Fix: edit the tclsh and wish Makefiles and add -rdynamic to the link
+command (if gcc is used, or -export-dynamic if ld is used).
