I installed it with Synaptic. However, it does not appear in the “Add to Panel” list or in any Applications menu. My successful workaround for this problem was to add to startup a “python /usr/bin/glipper” command. That does get it started with an icon on the panel, but it is still not in the list. So it does work, but I would appreciate it if someone could clue me in to the correct way to get it installed.
(FWIW, this was on an RPi.)
Follow these steps described below. I believe this process will work for you, as it did for me.
Execute the following to install glipper:
sudo apt-get install glipper
Now open Startup Applications GUI from Preferences, or from Control Center.
Click on Add.
In the Edit Startup Program > Command, copy-paste the following:
/usr/bin/glipper
You can write anything in the Name and Comment fields, those actually doesn’t matter much. The only thing that matter is the Command field.
This way, you’ve added glipper in Startup Applications. Therefore, glipper will appear on MATE panel every time you boot your computer. Just reboot your computer now to see it appear on the panel.
Hope it helps! 
What about /usr/share/applications?
If glipper is there, you can drag it to the panel.
I didn’t know about that. Thanks, @v3xx
Actually, no. You apparently misunderstood my post. I made it clear that it was working for me. The only thing I learned from your post is that, to start a .py file from /bin, you don't need to explicitly invoke the Python interpreter.
The reason I believe that it is not installed correctly is based on the following from the Glipper Manual: "To start Glipper, right-click on the GNOME panel and choose Add To Panel. Select Clipboard Manager in the dialog, then click OK. Glipper will appear in the panel then." There is neither "Glipper" nor "Clipboard Manager" in the Add To Panel dialogue list.
There is a folder there named "glipper". However, dragging that onto the panel merely gives one a shortcut to that folder, not the program.
I installed glipper and found it in Add to Panel>Indicator Applet Complete
I have no idea what that applet would have to do with glipper. If I attempt to add it to the panel, all I get in the panel is a block of text: "No indicators". Same with the plain Indicator Applet. Glipper itself definitely does not appear in the list as it is supposed to if correctly installed.
It is conceivable that the differences I am experiencing are attributable to fact that I am using the RPi distro.
I tried to do a little more googling regarding Indicator Applet Complete. As far as I could tell, its purpose is to make Gnome 3 behave more like Gnome 2. But, since we are starting from Gnome 2, I don't understand why it is even in the list.

That sounds like a real good possibility.
Since the upgrade to 15.10 failed, I had to start over with a new image for my SD card. This time, when I installed glipper, it added itself to my list of Startup programs, and it adds its icon to the panel properly. Though this thread had been marked “[SOLVED]”, the problem I described had never really been solved until this 15.10 release. (To the extent that there was any solution at all, I had already described that solution in my initial post.)
