Error build - can't find gnutls

Hi,

I am building the latest git master on 64 bit Linux using the following:

libtoolize --force
autoreconf -vi
./configure --with-system-libffi=/usr/lib/x86_64-linux-gnu
--with-system-libltdl=/usr/lib/x86_64-linux-gnu
make


One of the configure output lines reads:
checking for gnutls_global_init in -lgnutls... yes


Also:
/usr/lib $ find . -name '*ltdl*'
./x86_64-linux-gnu/libltdl.so.7
./x86_64-linux-gnu/libltdl.so.7.3.0
./x86_64-linux-gnu/libltdl.la
./x86_64-linux-gnu/libltdl.a
./x86_64-linux-gnu/libltdl.so


The make ends with:
