It kinda looks like Assistant is picking up the version of Qt that is shipped 
with the operating system, and not the one it came with.

You might try explicitly pointing at those libraries when you launch Assistant:

      igor at gmi:~/Qt/5.5/gcc_64/bin$ LD_LIBRARY_PATH=`pwd` ./assistant

and see if that takes care of it.
