homebrew
Is there a way to list all the homebrew packages explicitly installed by the user (they they installed directly using brew install)?
Note brew leaves doesn't do this. Over time formula can change change their dependencies leaving orphaned leaves that were never explicitly installed by the user or adding dependencies on previously explicitly installed packages.
I had a similar problem a while back that was caused by having my proxies set up funny. I ended up disabling them to get it to install.
Also, are you sure curl is installed correctly? You could try installing it manually as well: http://curl.haxx.se/docs/install.html
brew list and brew list --caskRunning brew list will show a list of all your installed Homebrew packages.
In addition, brew list --cask will provide the items installed using Homebrew Cask.
