I am a little bit confused about that.

On the page "supported platforms" there is written that PowerPC or PowerPC 64 is
a supported
platform, so that I can compile postgres WITH spinlocks.
http://www.postgresql.org/docs/9.3/static/supported-platforms.html

Or is there a problem on the specific machine? Or is there something disabled
in the kernel?

Best regards
Lars
