Yes it is the same thing as SuSE 11.1 (SLES = SuSE Linux Enterprise Server)



When I discovered I didn’t have a profile I did go back

to [1] and discovered the intel-ness of the testing. For those

interested the base is

kernel 2.6.32

gcc-4.3.4

glibc-2.11.1

I copied 

usr/portage/profiles/prefix/linux/ppc64

to 

usr/portage/profiles/prefix/linux-standalone/ppc64

and then replaced 

usr/portage/profiles/prefix/linux-standalone/ppc64/make.default

by the amd64 one and copied the legacy folder from the amd64 one

also.
