How to install Mono on macOS so mono works in terminal?
I'm trying to get a Mono install running on a mac (OS X version 10.10.5), and while the install states that it's completed successfully, I'm not able to call mono from the terminal.
To install it, I ran uninstallMono.sh as root to ensure we didn't have any leftover cruft, then ran MonoFramework-MDK-4.0.4.1.macos10.xamarin.x86.pkg. The installer appeared to complete successfully, but an attempt to call mono returns
-bash: mono: command not found
The mono framework does appear to be installed:

...but it isn't present in /usr/bin and attempting to find its executable using which mono returns nothing.

In OS X El Capitan, run the following in Terminal to support mono command
export PATH=/Library/Frameworks/Mono.framework/Versions/Current/bin/:${PATH}
