Description:

SoX depends on libpng for some reason. Why this is, I cannot quite understand, but the bottom line is that when run without libpng installed on the OS (e.g. headless server without X), it complains about a missing shared library.

Secondarily, why isn't SoX compiled against lame by default? This is infuriating when trying to set up new servers that I have to custom compile "The Swiss Army knife of sound". I understand that MP3 has all sorts of legal issues surrounding it, but it doesn't make practical sense to distribute a package that lacks functionality that would otherwise be available through manual compilation.

I have consistently had trouble with SoX when upgrading as can be noted from my forum posts [1]. Please fix this, or promote me to be the maintainer for this package.
