Comment (by grumpybozo):

 I don't claim the provided patch (which I just copied from what was
 applied as a fix upstream)  is the ''right'' fix, but it does fix the
 problems I see:

 1. On Snow Leopard, the current prebuilt MacPorts package of libgcrypt,
 when used via the current prebuilt MacPorts package of gnupg2, is broken.
 2. Packages built locally using mp-clang-9.0 (i.e. no {{{-isysroot}}}) on
 SnowLeopard (i.e. with  the MacOSX10.6 SDK)  still have the same failure..
