Emerge don't install man pages anymore. Because missed doman in ebuild.
Created attachment 307353 [details, diff] doman-rtorrent.patch "#man_MANS = rtorrent.1" in Makefile.am seems to have caused this would not really make sense to reconfigure the whole build system for this file
The patch by Julian Ospald at comment #2 fixes this issue in my computer.
I can verify this, though I think it simply a matter of the 'doman' being removed when the version was bumped from 0.8.9 to 0.9.1 (and so I'm not quite sure why comment #2 is refering to the Makefile.am). Most probably a simple editing mistake as various patches were removed at that juncture. 0.9.2 & libtorrent-0.13.2 are now available, and with the addtion of 'doman doc/rtorrent.1' the ebuild can be bumped keeping the one patch that is currently applied, ${P}-ncurses.patch. I've built using PORTDIR_OVERLAY and besides the same 'QA issues' warning ('report upstream') that effected prior builds, it works as expected.

At least there is no 'enable_trackers' anymore, and it took me a while to grep it out of the sources...
I've added the doman call to the 0.9.2 ebuild.
