google了半天, 才找到答案:

You need the ibrowse library. I’m not sure where to download it from (google wasn’t much help).

I managed to get around it by downloading the base system install from http://cean.process-one.net/downloads/ , extracting it into a temporary directory, then manually copying the ibrowse-1.4.1 directory from the [CEAN BASE]/erlang/lib/ directory, into my system erlang/lib directory.

Worked fine after that.
