Yes I'll agree that using the -f option with pacman is a bad idea.
I've stopped using it after my discussion with Gaeton about libltdl
before. However, I do wonder if it is the only problem since the
libltdl issue has happened with two different packages. I can see the
logic of pacman -Uf as being the problem, but might it also be
something to do with having the libtool and libtdl packages being
split [great idea with excellent reasoning] and the installation. I
used the -Uf option with pacman for the original build of the split
package (when calibre failed to run) and for the rebuild (after which
calibre worked). Something I didn't do when this happened to me with
calibre was run [ldconfig -p | grep libltdl], and check the ld.so.conf
cache. I'm not an expert I'm just trying to learn and wondering about
the installation process. I also don't want to inject a problem due to
misuse of my system into the general discussion that creates more
problems. Before anyone asks about my original reasoning for using -f
with pacman please read the post referenced in the reply by Martti

I wasn't trying to hijack this thread or change the subject. I thought
this line of reasoning was germane to the questions being asked.
Thanks for your patience and assistance.
