Always check the OS specific README files for special requirements or caveats.
Users running Linux should note that Elf is now the only binary type supported for Linux OSs. This means that binaries for ix86/a.out and AXP/ECOFF are not available with this release.
Users running FreeBSD 3.0 should note that only ELF binaries are provided with this release. a.out shared libraries are also included for compatibility purposes.
