Fastthread on x86_64?

[Alex Young]

Is this a known-bad combination? I'm installing onto Debian Etch, and:

$ ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux]

When I gem install fastthread, I get these:

In file included from fastthread.c:12:
/usr/lib/ruby/1.8/x86_64-linux/ruby.h:31:21: error: stdlib.h: No such

(many more errors follow)
...

I've probably forgotten something obvious, but I can't see what. Anyone
got any clues?

Never mind... apt-get install build-essential was the vital step.
