AUR package is not rebuild after shared lib deps change

[ee9b590be72a7469e34d35705fb7c598]

Even after apacman -Syu one of my AUR packages does not start (after a system update) because of shared libs that do not exist anymore:

$ sudo pacman -Syu
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
:: Starting full system upgrade...
 there is nothing to do
$ apacman -Syu    
:: Synchronizing package databases...
 core is up to date

 multilib is up to date
:: Starting full system upgrade...
 there is nothing to do

 aur                                                    22  22 [##################################] 100%
:: Starting full aur upgrade...
 local database is up to date
$ mu
mu: error while loading shared libraries: libxapian.so.22: cannot open shared object file: No such file or directory
$ 

Just apacman -S mu does not help, as it simply reinstalls from cache. I had to manually reinstall with --skipcache.

I would expect apacman -Syu to take care of this. It should never just successfully finish and leave the system in a state where installed packages are not able to run.

Also, it seems that a python upgrade went by unnoticed:

This feels just... wrong.

You need to do the rebuild yourself
