Ok. I just tried this:
#include <stdio.h>
#include <dlfcn.h>

int main(int argc, char **argv) {
  void *handle;
  char *error;

  handle =3D dlopen ("libncurses.so", RTLD_LAZY);
  if (!handle) {
    fprintf (stderr, "%s\n", dlerror());
    exit(1);
  }
  else {
    fprintf (stdout, "Opened libncurses successfully\n");
  }

  dlclose(handle);
  return 0;
}

built with the following command:
james@athos src $ gcc -rdynamic -o dlopentest dlopentest.c -ldl

And result:
james@athos src $ ./dlopentest=20
Opened libncurses successfully

Humm.. seems to work. Unfortunately I am getting a bit out of my depth
here. I still have a lot to learn about Linux programming it would seem
;-)=20

I am following up on another theory as well to do with the version of
gcc used to build mono. I will let you know if that makes any
difference.

Cheers,
James
