I think you would need a pypy 1.5.1 variant (I could be wrong) that 
would include the fix for the conversion and traceSignal functions.

I believe most have used the version (binaries supplied) that Jan D. 
mentions in his write-up.  And simply avoid using the conversion 
(toVerilog, toVHDL) and the traceSignal functions.  If you have both 
cpython and pypy you can work around the issue till the next pypy 
release.  Use pypy for the simulations and cpython for conversion.

Hope that helps,
