Why exactly? Cross-platform is pretty much dead if people start thinking that way. It's not just Windows either - I recently experienced the same sort of pain when trying to install a language on a Unix that wasn't MacOS or FreeBSD.
So you'd think that at least the install script is Posix-compliant and runs on your shell? Think again! Despite it starting with an innocent #!/bin/sh , the script was actually bash-only and used GNU-extensions all over the place, too...
