'pkg_create -b libgsf-1.14.5' fails

[Jan Henrik Sylvester]

After portupgrade to libgsf-1.14.5, package creation fails:

%pkg_create -b libgsf-1.14.5
tar: etc/gconf/schemas/gsf-office-thumbnailer.schemas: Cannot stat: No 
such file or directory
pkg_create: make_dist: tar command failed with code 256

The file is indeed not there. (It is not listed in pkg-plist, either.)

Is there something wrong with the port or with my system?

Thanks
Jan Henrik
