I had problems installing Audio::TagLib 1.64 from cpan due to an error
compiling at include/iconv_wrap.h. The issue seems to be to do with
versions of iconv.h for the mac osx 10.9 xcode. I was able to get it
working by doing the following.
1. downloaded 1.65_1 in the hope that issue might magically be resolved,
got same error:

2. tweaked the iconv.h wrapper to remove the cast:

3. compiles and installs OK, seems to work in my application.
Hope this is useful, many thanks for providing Audio::TagLib.
Cheers,
