This is reported by the following two shared libraries on my machine:

…/ruby-1.8.6/bin/digest.so: the (null)() function is unimplemented  
on this machine (NotImplementedError)  
…/ruby-1.8.6/bin/socket.so: the (null)() function is unimplemented  
on this machine (NotImplementedError)

Where in the sources do I check if this can be enabled/fixed on my  
machine?

I’m trying to verify my build of Ruby by running the tests under both  
the “test” and “ext” subdirectories. Some of these tests had  
dependencies on the presence of the above shared libraries, so I built  
those first. But later I ran into the above diagnostics, so I wasn’t  
sure how to proceed.
