Just seccessfully emerged mondo 1.47. But if you try to run mondoarchive it complains about a missing library: $ mondoarchive mondoarchive: error while loading shared libraries: libnewt.so.0.50: cannot open shared object file: No such file or directory If you link /usr/lib/libnewt.so.50 to libnewt.so.50.35, mondo runs fine, but without this tweak, it won't run.
please update to latest newt ( newt-0.50.35-r2 ) reopen this bug if it still fails
