The file is compiled for a Linux environment, as is made clear by the sentence
for GNU/LINUX 2.6.18, and the reason is that it uses shared libraries. This rules out a Mac, because, even though there are certainly MAC models running on Intel 80386 chips, none uses the Linux shared libraries.
On the other hand, though you may have a Linux distro installed on the Raspberry Pi (Debian or Arch, or ...) the
cpu architecture for which this file has been compiled is
Intel 80386, which differs greatly from the
ARM architecture appropriate to the Raspberry Pi cpu.
You will have to search for versions of this program which have been ported to different environments. The Pi's repos provide exactly this kind of functionality, i.e., a collection of programs typical of Linux, but recompiled to run on an ARM architecture. With Mac, the operating systems being different, you may end up searching for a different program, performing the same tasks.
