wine users - Dec 2009 - Can't install any winetrick

Hello! I've installed wine and wine bottler on Snow Leopard and trying to
install Neverwinter Nights 2 : Mask of the Betrayer and have a problem. I've
read here http://appdb.winehq.org/objectManager.php?sClass=version&iId=17426
that I need to install some winetricks first. I here is a problem, becouse after
few secount popups message with error:
09-12-09 11:53:53	Wine[3624]	###ERROR### Command 'sh
/Users/jankral/Library/Application Support/Wine/winetricks.sh divx' returned
status 1.
I tried to install NvN2 without any winetricks but installer requires .NET 2.0

I'm not sure about this, but I do believe that winetricks only works on
Linux(-like) systems...

I created new prefix, and everything seems to work properly.
