I built calibre-0.8.18-2 and everything worked fine. Last night Imagemagick updated from [ libMagickWand.so.4 (libc6,x86-64) => /usr/lib/libMagickWand.so.4 ] to [ libMagickWand.so.5 (libc6,x86-64) => /usr/lib/libMagickWand.so.5 ] and calibre refuses to run again with the error message "Runtime Error: Failed to load Imagemagick: libMagickWand.so.4: cannot find shared object file: No such file or directory".
Together with imagemagick-6.7.2.1-1, calibre-0.8.18-2 was released to the repos (the latter links to the former). But by already having a "calibre-0.8.18-2" package installed on your system (that you linked to an earlier imagemagick), you prevented the upgrade calibre-0.8.18-1 ==> calibre-0.8.18-2 to happen. So pacman thought your calibre was up-to-date when it was not. If you want to maintain custom packages, do not give them the same name as official packages, and be prepared for rebuilds. -- Gaetan
