I am testing AlumniOnRails  
([http://rubyforge.org/frs/?group\_id=2959&release\_id=17170](http://rubyforge.org/frs/?group_id=2959&release_id=17170)) which is  
based on Rails 1.2.6 (I know it’s outdated) and managed to get it up,  
installed the required gems, created and migrated the data and most of  
the basic alumni functionalities are up but one, the part that is broken  
seems to be missing a library and yet I can’t seem to find it after a  
few reasonable searches.

The logger shows _no such file to load – collections/sequenced\_hash_  
with a line within the controller having the code of _require  
'collections/sequenced\_hash_ which is quite obvious that the  
_sequence\_hash_ library is missing.

A few searches on Google shows a few references, one with the closest  
pointer is [http://collections.rubyforge.org/classes/SequencedHash.html](http://collections.rubyforge.org/classes/SequencedHash.html)  
but unfortuntely the source link is dead. Does anyone keep this kind of  
old file or point me to somewhere it is? Thank you
