[SOLVED] Missing libao.so.2 after update on 04/12/2010

Question

I use pianobar frequently, and I discovered yesterday after running pacman -Syu that pianobar was no longer working:
$ pianobar
pianobar: error while loading shared libraries: libao.so.2: cannot open shared object file: No such file or directory
$ ldd /usr/bin/pianobar
linux-gate.so.1 => (0xb7855000)
libfaad.so.2 => /usr/lib/libfaad.so.2 (0xb77f5000)
libao.so.2 => not found
libpthread.so.0 => /lib/libpthread.so.0 (0xb77dc000)
libmad.so.0 => /usr/lib/libmad.so.0 (0xb77c5000)
libm.so.6 => /lib/libm.so.6 (0xb779e000)
libc.so.6 => /lib/libc.so.6 (0xb7657000)
/lib/ld-linux.so.2 (0xb7856000)
$ ls /usr/lib/ | grep libao
libao.so
libao.so.4
libao.so.4.0.0
libaoss.a
libaoss.so
libaoss.so.0
libaoss.so.0.0.0
I'm assuming that libao has been upgraded from libao.so.2 to libao.so.4, which is what's causing pianobar to fail to start up. I came across a this website while looking for help, and I tried running ldconfig with the following result:
# ldconfig -v | grep libao
libaoss.so.0 -> libaoss.so.0.0.0
libao.so.4 -> libao.so.4.0.0
Why is libao.so.2 missing all of a sudden? How can I get it back? I appreciate any help. Thanks.

I just rebuilt pianobar using yaourt and it fixed the problem:
$ yaourt pianobar
$ ldd /usr/bin/pianobar
linux-gate.so.1 => (0xb776c000)

libao.so.4 => /usr/lib/libao.so.4 (0xb7704000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb76eb000)
libmad.so.0 => /usr/lib/libmad.so.0 (0xb76d4000)
libm.so.6 => /lib/libm.so.6 (0xb76ad000)
libc.so.6 => /lib/libc.so.6 (0xb7566000)
libdl.so.2 => /lib/libdl.so.2 (0xb7562000)
/lib/ld-linux.so.2 (0xb776d000)
$ pianobar

Sorry I posted. I hope I didn't bother anyone.
EDIT: Thanks for the help, skottish.
