Re: Installing eRuby on MacOS X

I recently got both working on Panther with the Apache and Ruby 
versions that come installed with the system.

It sounds like you're using your own manual install of Apache... are 
you using a manual Ruby install as well? Can you launch, e.g., irb, or 
run normal Ruby scripts?

The undefined symbol errors indicate that for some reason, mod_ruby 
can't load libruby. You might try recompiling mod_ruby and eRuby, but 
statically linking them against libruby.a.

I had a similar problem when I was trying to get RubyCocoa working 
before it had been updated for Panther... not sure what they changed to 
make it work with the dynamic library though.
