I'm trying to install eruby on OS X -- it's 10.2, meaning Ruby was
part of the standard install. My make gets this error:

gcc: /usr/lib/ruby/1.6/powerpc-darwin6.0/libruby.a: No such file or
directory

Googling around in the archives, I found this thread:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=utf-8&th=d0b4b77b7bdce612&rnum=3

And based on the advice there, tried installing RubyCocoa to get
libruby.a along with it. The RubyCocoa install seemed to go fine, but
libruby.a still isn't there.

Any pointers as to where I should look next would be greatly
appreciated.

Thanks,

Francis
