Several new build problems: devel/libgdata devel/gvfs www/webkit-gtk2

[Jan Henrik Sylvester]

After the security/gnutls update, I decided to "pkg_delete -r" it and 
rebuild all dependent ports (with a script that does "make install 
clean" for all ports I need). Several ports did not finish, but failed 
in www/webkit-gtk2, devel/libgdata, and devel/gvfs respectively.

www/webkit-gtk2 dies with:
./WebCore/platform/network/soup/ResourceResponse.h:31:26: error: 
libsoup/soup.h: No such file or directory

devel/libgdata dies with:
gdata/gdata-marshal.c:5:25: error: glib-object.h: No such file or directory

devel/gvfs dies with:
soup-input-stream.c:28:26: error: libsoup/soup.h: No such file or directory

I verified that the files are in fact installed and 
libdata/pkgconfig/libsoup-2.4.pc and libdata/pkgconfig/glib-2.0.pc 
contain Cflags including the include directories in question. I do not 
see a problem there or in the build logs before the headers are not found.

Here are the make outputs:

There are many other (up-to-date) packages installed, but I do not think 
that is an issue, since I did a similar build including the ports in 
question five days ago and there were no issues (and the gnome ports 
usually build with anything else installed).

What could be wrong or what should I look at next?

Thanks,
