Comment(by herzog@…):

 The description of the problem is not quite correct:
 The header files for the ppc and i386 plattforms of libffi are completely
 okay.

 The problem is the mechanism which glues together the headers for the
 different
 plattforms into a single universal header file.

 For example, everything works well, if the files

    /opt/local/lib/libffi-3.0.10/include/ffi.h
    /opt/local/lib/libffi-3.0.10/include/ffitarget.h

 are replaced by headers which include the appropriate headers from

                         ...libffi/work/destroot-ppc and
                         ...libffi/work/destroot-i386

 respectively. Too see this, replace the directory

    /opt/local/lib/libffi-3.0.10/include

 with the directory contained in the attachment 'include.zip'.

 Replying to [ticket:31459 herzog@…]:
 > Installation of libffi via '`sudo port -svk install libffi +universal`'
 > creates a header file '/opt/local/lib/libffi-3.0.10/include/ffi.h' whose
 number of `#if` statements does not match the number of `#endif`'s.
 > For example, '`sudo port -svk install py27-gobject +universal`' results
 in the following error code:
 > {{{
 > In file included from ffi-marshaller.c:24:
 > /opt/local/lib/libffi-3.0.10/include/ffi.h:53:1: error: unterminated
 #ifndef
 > }}}
 > This looks very similar to Ticket #25439 concerning an older version of
 this library.
