shared library path inconsistent from one host to another

I buil开发者_Python百科t my qt app so that all the Qt modules it uses are contained in the same directory as the executable. It works on the machine I used to build the app and I made sure to test this by removing those shared libraries everywhere except in the current directory of the app. Doing a ldd shows that its looking for those libraries in the current directory and putting the executable by itself fails to open the exectuable. So this is all good but when I transfer this directory to a host machine it still cant find those libraries. what could be the problem?

Is "." in the LD_LIBRARY_PATH on the 2nd machine?
Do you have the correct permissions on the library files?
