# NaCL has an odd compilation model (software by djb, who'da thunk it?)
# and installs the resulting binaries in a directory like:
# <nacl source>/build/<hostname>/lib/<arch>/libnacl.a
# <nacl source>/build/<hostname>/include/<arch>/crypto_box.h
# etc. Each of these is optimized for the specific hardware it's
# compiled on.
#
# It also builds both x86 and x86_64 copies if your compiler can
# handle it. Here we only install one copy, based on if you're a
# 64bit system or not. A --universal could come later though I guess.
