[pHash-support] Dependencies, and some build problems

[Nick Welch]

Hi, your dependencies list on the download page seems to omit libavcodec,
libavformat, and libswscale.  I had to install them for ./configure to succeed.

Also, running 'make' dies very quickly with compile errors. My gcc --version is
"gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1"

Here is the error output:
