Build failed when installing REE as it complains about OpenSSL

[damian]

I'm running Ubuntu 11.10 and can't install ree-1.8.7-2011.03, though installing 1.8.7-p352 worked fine. OpenSSL is installed. See below a snippet of the log from the build failure. I can't figure out as to why this is happening?

This is a ruby-build issue.

But I think you just need to pass some extra configure flags or something.
