Only way is to search files which have the inode number File::Stat#ino.  
File::Stat represents status of an inode and an inode may be associated
many file names.  

% mkdir foo
% cd foo
% touch a
% ln a b  
% ln a c
% ls -i
2032361 a       2032361 b       2032361 c
% ruby -e 's = %w(a b c).map{|i| File.stat(i)}; p [s[0]==s[1], s[1]==s[2]]'
[true, true]
% touch d
% ls -i
2032361 a       2032361 b       2032361 c       2032364 d
% find . -inum 2032361
./a
./b
./c
% ruby -r find -e 'a = File.stat("a"); Find.find("."){|i| puts i if File.stat(i).ino == a.ino}' 
./c
./b
./a
% 

But you might need to do Find.find("/") instead of Find.find(".").
