Error in installation?

[vizzerra]

Hello. I'm getting this error when trying to run finder--the error occurs with example data as well. Any help would be greatly appreciated.

Traceback (most recent call last): File "/data/selaginella/finder/finder", line 648, in <module> main() File "/data/selaginella/finder/finder", line 586, in main validateCommandLineArguments(options,logger_proxy,logging_mutex) File "/data/selaginella/finder/finder", line 235, in validateCommandLineArguments cmd+=" --runThreadN "+options.cpu TypeError: can only concatenate str (not "int") to str
