Its normal, as the symbols are duplicated. Anyway, Ruby could use some of 
dlopen() flags (supported by newer glibcs) to try to avoid such problems. 
PHP uses those glibc tricks to try to avoid these problems (and there are 
many..), although miracles aren't possible, of course :)
I would say that using RTLD_DEEPBIND in Ruby's dlopen mechanism would fix 
your problem.

Anyway, thats why usually the C libraries prefix all their functions with 
the library name..

The problem is: how to "fix" the problem without breaking compatibility with 
older tidy lib versions?
