Hi Desmond,
To check whether dlopen works correctly, please try the following
program, replacing <your_path> by actual example.so path

--------------- test.cc ------------------------------
#include <dlfcn.h>
#include <iostream>

void main ()
{
  void* ptr=dlopen("<your_path>/example.so",RTLD_NOW);
  if (ptr==NULL) cout<<dlerror()<<endl;
}
------------------------------------------------------
g++ -o test test.cc -ldl
./test

If this program will not print any error, then dlopen()
works correctly and an error is somewhere in TCL. In this
case try to debug what parameters are actually passed to
dlopen() when you do load 'example.so' inside TCL.

One more note: as you found that duplicated __builtin_delete
come from libTCL8.0.a, I guess that this library was not
compiled with egcs 1.1.x. I strongly recommend to rebuild
all C++ libraries with current compiler.

Regards,
Andrey.
