Libgcrypt 1.6.0 released and gunpg 2.x

[shmick at riseup.net]

this looks like a significant upgrade

if i have already compiled gnupg 2.x with libgcrypt 1.5.3, and i want to
use the new 1.6.0, do i need to uninstall gnupg & libcrypt and then
compile both again together, and re-install ?

gnupg 2.x would not work with the new libgcrypt if i just install it
alone, would it ? (im sure i have to do it all again...)
