bici There's not really a one line install option available, unfortunately. If you want to setup a gopher daemon such as gophernicus you can do so fairly quickly by slightly modifying their install method.
mkdir -p $HOME/gophernicus
mkdir -p $HOME/gopher-data
mkdir -p ~/src && cd ~/src
git clone -b 3.1.1 https://github.com/gophernicus/gophernicus.git
cd gophernicus
./configure --prefix=$HOME/gophernicus --listener=standalone --gopherroot=$HOME/gopher-data
make
make install
I didn't test it beyond verifying the compiled binary, but you should be able to start it using a custom proxy port application over localhost. If you had something else in mind, let us know and maybe we can offer more guidance.
