A quick workaround for this problem would be to change

  RDYNAMIC_FLAG = -rdynamic

to

  RDYNAMIC_FLAG =

in Makeconf.  But the real fix involves figuring out why Octave's
configure script thinks that linking with -rdynamic will succeed.

Can you tell me what happens if you compile (and link) a simple
program with

  g++ -rdyanmic foo.cc

on your system?  For example, a hello world program like

#include <iostream.h>
int main (void) { cout << "hello world\n"; }

Does it fail?  What is the exit status of g++?

Thanks,
