I've installed qt5.5 from PPA. But I'm getting following output.

As described in the PPA description:
i386 and amd64 packages for Trusty Ubuntu release.
Each package contains one Qt module and installs under the /opt/qt55 prefix.
Source /opt/qt55/bin/qt55-env.sh to set the correct environment.
therefore
source /opt/qt55/bin/qt55-env.sh
