in jsoncpp-src-0.5.0.tar.gz there's no scons.py like the README.txt file suggest.
there's no other build instructions.
Having the same issue, anyone able to fix this? I have been able to compile the code by hand, though it would be nicer to build directly from the releases.
It's simply a readme problem. If you have scons installed on your system you can simply call it within the directory of jsoncpp. so replace python scons.py with scons.
Please refer to the readme for instruction on how to install scons.
