I was having trouble getting lua support while rolling my own vim 7.4 on ubuntu 13.04.

config for vim 7.4 with lua on ubuntu 13.04

sudo apt-get install liblua5.1-dev
sudo mkdir /usr/include/lua5.1/include/
sudo cp /usr/include/lua5.1/* /usr/include/lua5.1/include/
sudo ln -s /usr/lib/x86_64-linux-gnu/liblua5.1.so /usr/local/lib/liblua.so
hg clone https://code.google.com/p/vim/
cd vim
./configure --with-features=huge \
	--enable-perlinterp \
	--enable-rubyinterp \
	--enable-pythoninterp=yes \
	--with-python-config-dir=/usr/lib/python2.7/config-x86_64-linux-gnu \
	--enable-multibyte \
	--enable-fontset \
	--enable-gui=gtk2 \
	--disable-netbeans \
	--enable-luainterp=yes \
	--with-lua-prefix=/usr/include/lua5.1 \
	--enable-cscope \
	--enable-largefile \
	--prefix=/usr
make VIMRUNTIMEDIR=/usr/share/vim/vim74
sudo checkinstall

Have you ran this for 14.04 and the latest version of the lua? The script is completing but the "-lua" is being displayed when I type ":version".
