Should probably look at at least bug 161764: 1. pinentry emerged without libcap installed tinkkis mirja # ldd /usr/bin/pinentry-curses linux-gate.so.1 => (0xb7f3e000) libncurses.so.5 => /lib/libncurses.so.5 (0xb7eeb000) libc.so.6 => /lib/libc.so.6 (0xb7dc2000) libdl.so.2 => /lib/libdl.so.2 (0xb7dbe000) /lib/ld-linux.so.2 (0xb7f3f000) 2. with libcap tinkkis mirja # ldd /usr/bin/pinentry-curses linux-gate.so.1 => (0xb7f60000) libcap.so.1 => /lib/libcap.so.1 (0xb7f4c000) libncurses.so.5 => /lib/libncurses.so.5 (0xb7f0a000) libc.so.6 => /lib/libc.so.6 (0xb7de1000) libdl.so.2 => /lib/libdl.so.2 (0xb7ddd000) /lib/ld-linux.so.2 (0xb7f61000) 3. -r3 with libcap installed (USE="-caps") tinkkis mirja # ldd /usr/bin/pinentry-curses linux-gate.so.1 => (0xb7f34000) libncurses.so.5 => /lib/libncurses.so.5 (0xb7ee1000) libc.so.6 => /lib/libc.so.6 (0xb7db8000) libdl.so.2 => /lib/libdl.so.2 (0xb7db4000) /lib/ld-linux.so.2 (0xb7f35000)
Adding arches as the maintainer is not responding in a timely manner. Should be good to go as it's stable on most other arches any way.
