Comment 4 for bug 1192275

it is very easy to get the link to the file.
go to lm14, run synaptic, mark the package of your choice for reinstalation, disconnect the network and click apply. there will be an error message with the link.
in my case it was http://archive.ubuntu.com/ubuntu/pool/universe/c/comixcursors/comixcursors-lefthanded-opaque_0.7.2-2ubuntu1_all.deb
if you don't have lm14 at hand or if you do not wish to switch from lm15, you can freely browse http://archive.ubuntu.com/ubuntu/pool/universe/c/comixcursors/ and download the file you need.
(note the version 0.7.2-2ubuntu1_all, I did not try 0.7.2-3)
after you have downloaded the file, right-click on it and select something like "install/open with package/software manager" and then install it providing your password.

to prevent updates:
tell lm's update manager to ignore updates for the package
tell synaptic to "package" -> "lock version" of the package.
