When running audio/picard, the following error is generated:

OSError: /usr/local/lib/libtunepimp.so.3: Undefined symbol "libiconv_open"

--
This error seems to be due to the fact that libiconv is not properly linked to libtunepimp.so.3.  This can be seen with:

$ nm -B /usr/local/lib/libtunepimp.so.3 | grep libiconv_open
         U libiconv_open
$ ldd /usr/local/lib/libtunepimp.so.3
/usr/local/lib/libtunepimp.so.3:
        libmusicbrainz.so.4 => /usr/local/lib/libmusicbrainz.so.4 (0x281be000)
        libz.so.3 => /lib/libz.so.3 (0x281eb000)
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x281fb000)

        libexpat.so.6 => /usr/local/lib/libexpat.so.6 (0x282db000)
$ nm -B /usr/local/lib/libiconv.so.3 | grep libiconv_open
00011ab4 T libiconv_open

Fix: This was the patch I applied (diff -Nru):



But, you could probably solve this in a number of ways.--YuTCtUVszBd9o6m7ku35Eyl78KoAlKWZai7fGcCodxCP3iHL
