Created attachment 368380 [details] aegisub-3.1.0-build.log [ebuild R ] dev-libs/boost-1.52.0-r6:0/1.52 USE="doc icu python threads -debug -mpi -nls -static-libs -tools" PYTHON_TARGETS="python2_7 python3_2 python3_3 -python2_6" 0 kB It appears that the directory /usr/include/boost/locale does not exist, although the header /usr/include/boost/locale.hpp does.
There seems to be something wrong with your boost package. Not only the header should be present, but there this thing earlier: > checking whether the Boost::Locale library is available... no Usually, I'd follow it up with "attach config.log", but the missing headers suggest the lib might indeed not be there.
media-video/aegisub-3.1.0 build when I built Boost with USE="nls": [ebuild R ~] dev-libs/boost-1.53.0-r1:0/1.53 USE="doc icu nls python threads -debug -mpi -static-libs -tools" PYTHON_TARGETS="python2_7 python3_2 python3_3 -python2_6" 0 kB Hence it appears that aegisub is missing a boost[nls] dependency.
Please report this problem also upstream: configure should check if boost is compiled and installed correctly and exit with error when it is not.
