The current stable version autodetects libcap so please request stable marking
for it if you think it's otherwise good to go. 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)
