Recompiled it on an up to date 64 bit fedora 15 machine. Thats much
easier, but unfortunately just the same error message when I run it.
Disabling SELINUX makes no difference btw.
Additional info:
/var/log/messages also contains:
kernel: [17259.970316] linux[14027] general protection ip:602a2e7f
sp:7fffe11a09e8 error:0 in linux[60000000+4aa000]
Here are the last few lines from a strace:
write(2, "Checking syscall emulation patch"..., 46Checking syscall
emulation patch for ptrace...) = 46
