 dnl If we have to use the old method of overriding connect (i.e no
 dnl RTLD_NEXT) we need to know the location of the library that
 dnl contains connect(), select(), poll() and close()

   dnl We need to find the path to the library, to do 
   dnl this we use find on the usual suspects, i.e /lib and
   dnl /usr/lib
