Well, '-I/usr/local/include' appears before ' -I./opencdk
-I../lib/opencdk', that's why it picks wrong opencdk.h I think.

lib/Makefile.am has the following code:

-----------------
AM_CPPFLAGS = -DLOCALEDIR=\"$(localedir)\"                              \
        -I$(top_srcdir)/lgl -I$(top_builddir)/lgl                       \
        -I$(top_srcdir)/includes -I../includes                          \
        -I$(srcdir)/x509                                                \
        -I$(top_srcdir)/libextra -I$(top_srcdir)/lib/openpgp/   \
        $(LIBGCRYPT_CFLAGS)

if ENABLE_OPENPGP
SUBDIRS += opencdk
SUBDIRS += openpgp
AM_CPPFLAGS += -I$(srcdir)/opencdk -I$(top_srcdir)/lib/opencdk
endif
-----------------

I guess "-I/usr/local/include" appears here in place of $(LIBGCRYPT_CFLAGS). So the 
problem probably could be fixed by changing -I flags order in
AM_CPPFLAGS, i.e. placing opencdk stuff before $(LIBGCRYPT_CFLAGS). But
I'm not sure, I cannot test it at this moment, will be able to check a
bit later.
