New output is below.

[One guess could be dvips return errorlevel 1 in the first case. That is why stat is wrong.
The other cases does not work because of the space in the file name and because there
is an option i.e. -v]

checking dvips version...
CMD: C:\Program Files\TeXLive\bin\win32\dvips.exe
STAT:1, MSG=This is dvips(k) 5.94a Copyright 2003 Radical Eye Software (www.radi

CMD: C:\Program Files\TeXLive\bin\win32\dvips.exe --version
STAT:1, MSG='C:\Program' is not recognized as an internal or external command,
operable program or batch file.

C:\local\netpbm\bin\pnmcrop.exe -verbose yes
