Error while trying to install latest rawhide on pSeries

[Joy Latten]

Yesterday I copied the boot.iso from
latest /pub/fedora/core/development/ppc/image/pseries 
and used it to start an installation via http or ftp on a 
pseries (squadron). I received the error below. I am not sure
I understand why anaconda is complaining. The directory I entered
for installing was /pub/fedora/linux/core/development/ppc/.  
 
Running anaconda, the Fedora Core system installer - please wait...
Could not find platform independent libraries <prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
Traceback (most recent call last):

you may safely reboot your system
