[Wine] winetrick is not working anymore

[whatbug]

Hello I have been trying to make some game run under my Arch-linux, but d3dx9 was needed so i installed it by:
winetricks d3dx9

Even so i got this error when running PES2011:
err:module:import_dll Library d3dx9_30.dll (which is needed by L"D:\\PES2011\\PES2011.exe") not found
err:module:LdrInitializeThunk Main exe initialization for L"D:\\Portable\\_Juegos\\PES2011\\PES2011.exe" failed, status c0000135

But today winetricks was updated to version winetricks-20101008-1, and now if i do winetricks d3dx9 (or any winetricks command), i get this error:
You're using a 64-bit WINEPREFIX, most of winetricks hasn't been fixed for win64 yet.

My arch install is 64-bit, but wine is configured as windows 98.
After reading http://wiki.jswindle.com/index.php/Wine_Prefixes
I dont see any way to set a 32-bit WINEPREFIX.

any ideas?
