pigpen from windows? ( whoami error )

Dear pig users,

I currently use pig via the grunt shell, but would like to be able to also use the eclipse pigpen plugin.

I have pigpen installed on a win XP box and see the pig-menus in eclipse.  Pigpen appears to connect via org.apache.hadoop.fs.FileSystem correctly but then complains that "whoami" cannot be run.  

Since I actually happen to have cygwin installed with a whoami at c:\cygwin\whoami.exe ( /usr/bin/whoami from within the cygwin environment ) is there a way to tell pigpen to use c:\cygwin\whoami.exe?  Is there a better work-around?  Has anyone been able to use the pigpen plugin from windows to submit jobs to a distant hadoop cluster?

Many thanks for your help,
Avram

Unfortunately, yes.  
Neither c:\cygwin\bin nor c:\cygwin in my PATH resolves the error.  It still can't find 'whoami'.

I have not tried it, but do you have c:\cygwin and c:\cygwin\bin in your 
PATH ?
