[Rivet] issue with mkhtml complaining about ReadError

[Raghav Kunnawalkam Elayavalli]

Yeah, Im just reinstalling yoda 1.5.9 (just rerunning my rivet-bootstrap-lcg) in the same location now as suggested. 
But it is strange, since i cant tell which file is causing that, since that particular line which is being printed out
>>>        '4.000000e+015.000000e+010.96767520.05649410.0564941' on line 9
if not there in any of the files! 

I also think its an email formatting thing. its all one line with tab spaces between the points. 

As soon as this re-installation completes, ill run it with the setting for the data path and let you know if it works. 

Cheers
Raghav
