mrjob installation - class PlatformName not found

[Roman]

Hi,

I've installed the current version of mrjob (v0.4) and I was testing the first tests.
I've extended mrjob.conf with my hadoop_home and put it in /etc.
The command  locally works good. But running it on hadoop I get an error that PlatformName class was not found.
I'm sure that hadoop path is ok, since I use hadoop in pseudo distributed mode for another tasks and it works.
What could be a problem with this class?

Thanks,

Roman
