Comment (by kencu):

 using apple-gcc42 on a simple hello, world c program we see this:
 {{{
 $ gcc-apple-4.2 -Wl,-v  -fstack-protector -o hello1 hello.c
 collect2 version 4.2.1 (Apple Inc. build 5666) (dot 3) (MacPorts apple-
 gcc42 5666.3_16) (i686 Darwin)

 }}}

 so in this case, the gcc configuration has correctly noticed that the
 libssp is needed on this system, it has correctly added the proper library
 links to the link line, but the libraries, at least one of them, are not
 there to link against, as presumably they are supposed to be on this
 system.
