Your system (Mandrake 10) is not exactly the same as any computer we have here. You can either
(a) download the linux_glibc22 binaries and see if they work,
OR
(b) download the afni_src.tgz source code and compile it for your system, and see if it works -- if you decide to do this, probably Makefile.linux_gcc32 is the correct make script for you to use.
