IOError while running wireshark from build directory for pyreshark

Hi, I'm trying to build wireshark after building from pyreshark. When I run the command WIRESHARK_RUN_FROM_BUILD_DIRECTORY=1 ./wireshark

I get the following error.

 Can't open Pyreshark init file: /home/paavu/wireshark-1.12.4/python/pyreshark.py
    IOError: [Errno 2] No such file or directory: '/home/paavu/wireshark-1.12.4/python/pyreshark.py'

The actual path of pyreshark.py is wireshark-1.12.4/plugins/pyreshark/python/pyreshark.py

Any help is appreciated
