Yes, that is the problem.  This is  a standalone script that is run at 
install time, so it does not have any information about the build 
toolchain. In retrospect it should have been passed more information 
about the build tool chain that was used.

This is what we want:

#    dumpbin (Windows)
#    objdump (MinGW on Windows)
#    ldd (Linux/Unix)
#    otool (Mac OSX)

Trouble is dumpbin and objdump might both be in the PATH on Windows. 
You don't really know which one to use.     I wonder if you found both 
if you could call something on each of them with one of the binaries, if 
you could figure out what tool would work better with it.
