Unfortunately I don't remember the exact program, I remember  
installing an open source program (something like a network monitor  
or something) and it wouldn't work on every version.

I also remember hearing that perl 4 to perl 5 had a lot of  
incompatible changes, just look for a doc on migrating from perl 4 to  
perl 5.

I've also run into quite a few pieces of software that needed  
specific versions of java.  Oracle being the worst; I still haven't  
found the right version of java to get it to run.

You must be new here. :)  The rails team didn't handle the 1.0 to 1.1  
upgrade well, and worse, all the web host services  upgraded without   
doing proper testing.  Hopefully they have learned their lesson  
early.... :)

The rails framework is still undergoing very rapid development, and  
so leaving your app in the hands of the system installed version is  
not a good idea.  To help with this, you can either lock your rails  
app to a specific installed version, or you can install the whole  
rails tree within your own app, which will keep it from ever being  
broken by a rails upgrade.
