I found this problem by compiling libtorrent-rasterbar-1.2.1 with python3_6 support only to find the Python module linked to libboost_python27.so.1.70.0. This, of course, breaks it. The fix is simple: https://github.com/stefantalpalaru/gentoo-overlay/blob/79b19b8292c87f4cf25307f135be3511f5e6f7cf/net-libs/libtorrent-rasterbar/libtorrent-rasterbar-1.2.1-r100.ebuild#L85 I also fixed another problem, in my overlay: "-Os" overriding the user's CXXFLAGS when compiling the Python module.
I don't believe this issue is relevant any more as versions in Gentoo contain: --with-boost-python="${EPYTHON#python}"
Nothing changed. EPYTHON is something like "python2.7", so `--with-boost-python="${EPYTHON#python}"` ends up being `--with-boost-python="2.7"` when what you really need is `--with-boost-python="boost_python27"`.
I have a problem during emerge that could be possibly related to this. When I launch: emerge --update --newuse --deep --with-bdeps=y --changed-use @world I have as a result: !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: net-libs/libtorrent-rasterbar:0 (net-libs/libtorrent-rasterbar-1.2.1:0/9::gentoo, ebuild scheduled for merge) pulled in by (no parents that aren't satisfied by other packages in this slot) (net-libs/libtorrent-rasterbar-1.1.13:0/9::gentoo, ebuild scheduled for merge) pulled in by <net-libs/libtorrent-rasterbar-1.2[python,python_targets_python2_7(-)?,-python_single_target_jython2_7(-),-python_single_target_pypy(-),-python_single_target_pypy3(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-),python_single_target_python2_7(+)] required by (net-p2p/deluge-1.3.15-r3:0/0::gentoo, installed) ^ ^^^ It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. The following packages are causing rebuilds: (dev-libs/boost-1.71.0:0/1.71.0::gentoo, ebuild scheduled for merge) causes rebuilds for: (net-libs/libtorrent-rasterbar-1.2.1:0/9::gentoo, ebuild scheduled for merge) (net-libs/libtorrent-rasterbar-1.1.13:0/9::gentoo, ebuild scheduled for merge) (media-video/mkvtoolnix-37.0.0:0/0::gentoo, ebuild scheduled for merge)
If you want a Deluge version that supports the newer libtorrent-rasterbar, there's net-p2p/deluge-2.0.3-r2 in my overlay: https://github.com/stefantalpalaru/gentoo-overlay

I have the same problem. I had to build with USE=-python_targets_python2_7
(In reply to Paolo Pedroni from comment #5) > I have the same problem. I had to build with USE=-python_targets_python2_7 Scratch that, I wrote too soon: it still links with libboost_python2.7.so The only way is applying the OP's fix.
