[PD] pd on macbook pro

[patrick]

hi,

should i install ubuntu 32 bits or 64 bits on a macbook pro (intel 64 
bits). if i go for ubuntu 64 bits, will i be able to use pd-extended or 
be able to compile most of the externals for this architecture? OR maybe 
it's possible to have the OS in 64 bits, but using the 32 bits version 
of pd???

thanks,
pat
