nope. you need an older linux. glibc is only backward compatible
but not forward compatible. if you copy a binary that was built with
a newer glibc to a machine with an older glibc, you get this failure.
there are ways around this, but they are messy.

it is probably easiest to just recompile on the OSC machine.
