### 
### This test case is to verify that dyld cannot be tricked into loading 
### the "same" library twice. 
### 
### The tricky scenario is:
###  1) a library dyld is to load is specified with a symlink path
###  2) the library the that is the target of the symlink is already loaded 
###  via a different path.  In this case becuase of DYLD_LIBRARY_PATH.
###
