EDIT: It seems that miranda is again distributed as a .tgz archive, therefore revert back to the original instructions here. This is little walk-through for installing the Miranda programming language on OS X. There are the original instructions here, but they things have changed a little since that document was written. Hence this little write-up. Firstly, download the OS X tarball from the Miranda downloads page or the direct download link. Open your OS X Terminal (search for it in Spotlight) and go to the directory the tarball was downloaded to. Then type  sudo tar xpf mira-2032-MacOSX.tar -C / This installs bunch of files in your /usr directory, hence the required su access. That's it. Just run mira  and off you go. If you know about a nice IDE or editor with syntax highlighting please post it in the comments.
