I'm trying to get eRuby and mod_ruby running on OS X (Panther). 
mod_ruby seems to be working fine, but if I try to enable eRuby,
Apache can't start up and writes the following to the error log:

dyld: /usr/sbin/httpd Undefined symbols:
_rb_cObject
_rb_check_type
_rb_data_object_alloc
_rb_define_class_under
_rb_define_method
_rb_define_module
.....

So I'm guessing it's trying to dynamically link to libruby and
failing...or something...I have no idea what to do about that.  Any
ideas?

I found quite a few postings with the same problem as this, but
unfortunately couldn't find any answers :-(

Thanks,
  Kevin
