Qtnx

ok, today I am trying to build qtnx:

git clone https://github.com/gw280/QtNX.git
cd QtNX/
cd nxcl/
tweedleburg:~/QtNX/nxcl # autoreconf -is
configure.ac:19: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
libtoolize --force
aclocal
autoheader 
automake --force-missing --add-missing
autoconf
./configure
