[racket] Program compiles with racket fails when invoked with execl()

Consider the simple Racket program

#lang racket
(+ (read) (read))

When this is compiled using raco, the executable produced works exactly as
intended, reading two integers on standard input and printing their sum.
However, when I run the C program

#include <unistd.h>
int main()

where "aplusb" is the name of the Racket program, it exits immediately with
the errors:

with-input-from-file: expects type <path or string> as 1st argument, given:
#f; other arguments were: #<procedure>

 === context ===


How can I fix this problem? I am using Racket v5.0.1 on Ubuntu 9.10 (i386).
