pkgsrc notes:
I've left the build against a private libassuan with GNU-pth support
alone for now, just updated libassuan to 1.0.5. We might build
pkgsrc/libassuan against pkgsrc/pth at some point, but this needs
to be checked for side effects. (As this pkg doesn't export a library
which might propagate the pth dependency, the possibility of
pthread-pth conflicts should be limited. Other uses of libassuan
need to be checked.)
Beiing here, support DESTDIR.
