Okay...I think I'm either an idiot or going slowly insane.  I'll admit 
I'm not the most savvy C programmer but the following code gives me an 
error:

## Source File##
#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>

int main() {
        char *line;

        line = readline("Test: ");

        return 0;
}
##Source File##

##Error##
/var/tmp//ccqxIZxQ.o(.text+0x25): In function `main':
: undefined reference to `readline'
##Error##

What sucks is that readline() seems like it would be the perfect 
solution.  I'm not doing anything special but my I don't want to start 
getting into bad habits like using gets().
