Caution: See Missing Libs Section
Someone on the Beginner's Section was having problems and asked what went wrong. I hadn't used veracrypt since I built the packages in the above post. Attempting to create an encrypted folder I discovered that there was nothing intuitive about it.
Fortunately, the veracrypt publishers provide a tutorial,
https://www.veracrypt.fr/en/Beginner's%20Tutorial.html. Carefully following the tutorial step by step I was able to create and copy files into it; later reopen it, open the files within in the respective applications and copy files from it. I recommend that you print it as a pdf so that it is available without having to go on line.
Except as noted below, I haven't tried anything fancy. Adding its file-type to Rox's Customized Right-Click menu accomplishes nothing. However veracrypt is started the desired folder --even if it is displayed as selected-- must still be selected by clicking the "Select" button and file-browsing to it.
When you open a folder rox's window will display something to the effect that it "can not stat". There might also have been an error message. Still, I could successfully use the folder with one very significant exception.
Caution: Do not attempt to directly create a file in that folder, e.g. Right-Click, New>file. Doing so seems to have destroyed the folder's previous contents without creating anything.
I have not, as yet. tried to delete a file from a veracrypt folder.
Remember, when you're finished with the folder to click the "Dismount All" button. Also, double check that veracrypt is actually closed, i.e., doesn't appear on your taskbar. Veracrypt will allow you to have two or more instances running. If you create an encrypted folder with the second open window, not having closed the first, veracrypt may still be focused on the folder selected in the first Window: you may accidentally overwrite its password and otherwise screw thing up.
IMHO, veracrypt could use some work such as warnings when you are about to do something dumb. Still, if used with care it does what is expected of it.
Missing LIbs: This is very annoying. I don't recall under which Puppies I assembled the pets and SFSes. It functioned correctly under them. I assume the 64bit version was built under Xenialpup64 as it functions properly there. Under other Puppies, after installing I ran ldd which showed "no missing libraries". I hadn't tested dpup-stretch, but after receiving a report of libraries missing I rebuilt the 32-bit and re-uploaded.
Testing the latter under Xenialpup32, again ldd reveals no missing libs. Everything works until you attempt to decrypt a folder. See attached screenshot.
Revisiting the veracrypts website revealed (a) several patches in the last couple of months, but more troubling (b) separate builds for separate major distro's versions; and (c ) a 32-bit package of questionable utility (no SSE2 support). For my purposes, it may make more sense to see if the Windows package will run under Wine than produce several 32-bit linux packages lacking SSE2 support.
