Important note the nettle bundle don't work on a machine that doesn't have nettle installed :
make: fatal errors encountered -- cannot continue *** Error code 1
I was under the impression that Nettle's Makefile will only work with GNU make. That was the case a few versions ago, but I haven't tested with 1.13.
That requirement should (AFAIK) be gone in Nettle 1.13.
