Ok, I found the solution on the Ubuntu site. The more I use Linux, the more I like it!

Here is how to do it in Linux Mint...Installing Files to Palm Pilot in Linux
Click on System, Preferences, Palm OS Devices to open gnome-pilot program. Click the Conduits tab, scroll down to File, click Settings and choose Enable.
Right-click on a file you want to put on your palm (a .PRC or .PDB) and select Open With Other Application... Click the arrow to expand and select Open With Other Application, Custom Command, and type: “gpilot-install-file --later” or leave off the “--later” to sync immediately. Click OK. Now, whenever you double-click on a prc, it'll be set to install on the next hotsync.
You can get the visual confirmation of having installed the files by checking the log file on the PDA after the hot-sync.
