https://pypi.python.org/simple/peak-rules/ seems to be broken. It does not list any packages which is very strange. Earlier, it was mostly providing PEAK-Rules>=0.5a1.dev-r2713.
From what I can tell, the PyPi page for PEAK-Rules does not have any packages available for installation, as you suspected in your question.
The solution is to install the PEAK-Rules dependency yourself, then install TurboJSON afterwards.
First, run:
easy_install http://www.turbogears.org/2.1/downloads/current/PEAK-Rules-0.5a1.dev-r2686.tar.gz
This should install PEAK-Rules 0.5a1.dev-r2686 successfully, which will satisfy the TurboJSON requirement of PEAK-Rules>=0.5a1.dev-r2600.
Now, if you run (sudo) easy_install -U TurboJSON, the installation should work as intended.
