Debian and ruby don’t like each other. Thats no secret. In the rails support channel it regularly happens that people come up with the most obscure error messages about missing stuff. You will hear 3+ people asking “what distro” but they know the answer already.

So what wen’t wrong? How did they come up with the brilliant idea to split the standard library into 34 different packages. I just can’t see how something moronic like this can even get started considering that a standard library is all about raising the status quo of the language by providing some shoulders to stand on so people can reach for higher goals.

the buckblogs here: “Some brilliant (and I use the term extremely loosely) Debian package maintainer decided to break Ruby into a million little pieces. They must have been big-time haters of Ruby, because the only reason I can think of for doing this is to make it as difficult as possible for Debian users to install a fully-functional Ruby on their system.”

If you need help installing rails on Debian you can read about it in the wiki.

However, I strongly recommend to move [gentoo.org] on [freebsd.org].
