I think most languages have a really difficult to configure environment if you mess it up or need to keep multiple versions around. Windows is especially bad about it because of the java_home variable. Mono is a mess to configure on Linux, or at least the last time I tried it to learn F#. Java is actually nice in that a lot of distros are packaging a version manager for it. Arch and centos lead the pack in this. Although cent continues to be a mess about how many jdks and Jres are available.
