[Wine] error on install with ps3

[Pakman]

i have just downloaded the course code for wine for my ps3 but when i run './tools/wineinstall' i get the error message 'port.c:183:2: error: #error You must implement wine_switch_to_stack for your platform'

i also get the error after i run 'make' (after i run ./configure' and 'make depend'

now is it because wine does not support ps3??
or is there something i am doing wrong?
