When I try running ex22 like Jed suggested it works fine.<br>
<br>
When I try running ex45 like Barry suggested it runs but it does not seem to recognize two options.<br>

Also, I am getting an message saying that it is running it with the debugger and I should rerun ./configure to turn it off and it will run 2 or 3 times faster. Does that mean that the installation always uses the debugger or never uses it? I thought I would like it keep it for testing, assuming i figure out how it works, but then turn it off for serious runs.</div>
