Is there a way to get the previous version of any package?

What is odd is that while the latest version of wireshark (1.2.6) compiles and runs fine under X11, it only reads the first couple of dozen packets of a live capture off the wire and then seems to stop capturing (the window doesn't continue to scroll upwards with fresh packets like it used to do).  Then when I explicitly stop the capture by clicking on the "Stop Capture" button, I get the following error:

Someone on the wireshark mailing list thinks that it could be due to changes in zlib 1.2.4 that wasn't there in zlib 1.2.3.  As such, I'm trying to uninstall zlib 1.2.4 and recompile wireshark 1.2.6 with version 1.2.3 of the zlib package just to see if he's right.

I experienced the same wireshark problem today (on Snow Leopard), and learned that zlib 1.2.4 was the problem from your thread on the wireshark list:

Yes, you can go back to zlib 1.2.3; doing so fixed the problem for me. Just follow the instructions in the how-to:
