gnutls/gnutls.h: No such file or directory

[Leo]

I have gnutls installed with prefix /usr/local/unix/gnutls and emacs
trunk used to build fine on OSX with:

PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/unix/gnutls/lib/pkgconfig:/usr/local/unix/dbus/lib/pkgconfig
 ./configure --without-jpeg --without-gif --without-tiff

But today I am getting this error:

The following two lines in src/Makefile seems relevant:

,----
| LIBGNUTLS_LIBS = -L/usr/local/unix/gnutls/lib -lgnutls  
| LIBGNUTLS_CFLAGS = 
`----
