I knew I would be bitten at some point by this. The problem is that my
GLIBC (/lib*/libc.so.*) is newer than yours. "__sched_cpucount" is a
function which exists in GLIBC 2.6 (and later) but not in earlier
versions. You can find out about your version by running:

/lib64/libc.so.6

In my case it prints:

GNU C Library development release version 2.8.90 (20080825), by Roland
McGrath et al.
[...]

In yours the version is presumably 2.5 or older. I do not see any simple
way to fix that - other than compiling GCC on an older Linux version. I
plan to look into this using VirtualBox, but it might take a while.
(Other solution for you: Compiler GCC yourself.)

:-(
