How to load Edgy version of a package onto Dapper?

[Larry Alkoff]

I run Dapper 6.06 on my Desktop machine and recently loaded Edgy 6.10 on 
a Laptop.

The Laptop loaded a much better version of Vim (7.1 vs 6.54).
When I try to update the Vim package on the Desktop it offers
only the current 6.54 version.

How can I get the Edgy version onto Dapper?
