Can confirm that =media-gfx/slic3r-9999 is not affected by this issue.
Can confirm, both that I hit this bug (the one in the title about expected class-name), and that -9999 builds without issue.
Created attachment 595038 [details, diff] boost-fix.patch I ran into this issue while rebuilding slic3r-1.3.0-r1 after boost was updated. Applying this patch allowed to rebuild successfully.
