Unable to compile: Cannot find source file "fastpaths_ppc.cpp"

Trying to compile, have the following error. Possibly a missing dependency?

/bin/bash: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, with unknown capability 0x41000000 = 0x13676e75, with unknown capability 0x10000 = 0xb0401, stripped
