As others pointed out, the above is correct.  It found debug information 
for ``entry-point'' and then tried to use it.  Only to barf because the 
the corresponding source files were not installed.  There's not much GDB 
can do when a user's program contains debug info but is missing the 
corresponding source.

What happens if you enter:

	(gdb) list main
