By default libsodium is used. Only if --enable-nacl is specified, then nacl will be used instead of libsodium. Pass locations of nacl headers and libraries by using the following options: --with-nacl-headers=/home/me/somewhere/nacl-20110221/build/469/include/amd64/ --with-nacl-libs=/home/me/somewhere/nacl-20110221/build/469/lib/amd64/
