Title: [update] netpbm-10.59.00

Ported from MacPorts to build with clang4/Xcode-4.4.1.
It can build both 10.59.00 and --HEAD.

## note

- The current formula fails to build both 10.35 and --HEAD with clang4

- Using source bundle from gentoo distfiles in a mirror of US gov
- The official tarball provides super stable versions only: 10.35.xx
- Tarballs from the link of sourceforge viewvc have unstable checksum

- Drop the super stable version netpbm
- It requires old version libpng
