calibre-0.9.41 added an optional, experimental new database backend. Announcement and details are here: http://www.mobileread.com/forums/showthread.php?t=218937 If this backend is enabled, dev-python/apsw is required.
I observed something related for calibre-1.0; I'm not sure whether I should report it as a new, separate bug. In my setting it seems that calibre-1.0 always depends on apsw. I will attach the output of the unsuccessful "cave resolve" (paludis' alternative to "emerge") before apsw was installed, and the output of "cave info" (for my use flags and system environment) for the, then, successfully installed calibre-1.0.
Created attachment 356868 [details] output of "cave resolve" (like "emerge") for calibre-1.0 with apsw not installed
Created attachment 356870 [details] output of "cave info =app-text/calibre-1.0::installed" (installed after manually installing apsw)
Created attachment 356958 [details] build.log
I can confirm the same with calibre-1.0: ImportError: No module named apsw and a bit later: install: cannot stat ‘/tmp/tmpfs/portage/app-text/calibre-1.0/image/usr/etc/bash_completion.d/calibre’: No such file or directory !!! doins: /tmp/tmpfs/portage/app-text/calibre-1.0/image/usr/etc/bash_completion.d/calibre does not exist whole build.log attached.

All our calibre ebuilds depend on apsw now.
