No.  That code snippet is carefully prepending the Qt directories onto
the existing values of PATH, MANPATH and LD_LIBRARY_PATH.

It might be a little safer to add $QTDIR/... onto the end of the other
values rather than the beginning - that way you can be certain that
Qt commands will not replace non-Qt command with the same name.
