I ran my usual gwcheck for 8.0.1 on Linux

I get the log file and parse it through gwmbsize and it says it's done (rather quickly, mind you) but it outputs a 1 KB file with just the header

does gwmbsize no longer work with 8.0.1 or is it because POA is on Linux now?

Or is there any sort of other nice utility that'll show the sizes per user in a semi-readable format (the log file isn't the most friendly).
