spu-gcc -Wall   hello_spe.c -o hello_spe.elf

Apparently I had a few attempts at installing various version of libspe2. I
might have copied some files across manually and forgot to clean up
afterwards---I can't remember. Anyway, the sample compiles and runs:

$ ./hello_ppe.elf
Hello world!

This tallies with my experience from before: I can write code (like
hello_spe.c above) that I know is running on the SPUs, but the problem is
just with the spufs. Michael Ellerman's previous reply about the kernel
patch looks like it should solve the problem, if only I knew how to compile
the 3.10 kernel under my mix of firmware (3.55) and OtherOS++ (using reboot
otheros/reboot package files to start linux from within the PS3 interface).

Anyway, thanks for the reply. I'm not sure if the results are any good for
you, but maybe it helps?
Thanks,
dec
