Hi,
I just installed YT and it's failing at the very start.

ImportError: libpng16.so.16: cannot open shared object file: No such file or directory

Adding the path to the libpng16.so.16 library gets me to here (it also seems strange that the .so file was not already in the LD_LIBRARY_PATH - is there a hint in there somewhere?):

Anybody come across this kind of error before.
