Install error with dat using npm on MacBook Pro (Intel version)

I am reporting:

an install issue as follows:

% sudo npm install -g dat

autoconf is required, but wasn't found on this system ./configure: line 5: ./configure: No such file or directory /usr/local/lib/node_modules/dat/node_modules/sodium-native/preinstall.js:119 if (err) throw err ^

Is there a fix for this? I can try installing autoconf but it looks like there are other issues as well. Thanks.
