Try altering the LIB_DEPENDS to this:

LIB_DEPENDS+=   curl:${PORTSDIR}/ftp/curl \
                 gcrypt:${PORTSDIR}/security/libgcrypt \
                 xml2:${PORTSDIR}/textproc/libxml2 \
                 gnutls:${PORTSDIR}/security/gnutls


And rebuild. To test, you could run:
make lib-depends (this will just check if you meet the library dependencies)
