Cannot make

Hello! today I tried to install Eloncoin again from source code. I cloned the most recent sources. And passed these commands and got this

./autogen.sh
export BDB_PREFIX='/usr/local/db4'; ./configure BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include" --with-boost-libdir=/usr/lib/x86_64-linux-gnu --with-gui

make
