[Phash-support] Compiling

[Kiran Lall]

Hi,

I've been trying to get up and running on OS X, with a couple of problems.
1: ./configure staright up falls down on the libswscale dependency. I
found it was to do with this:
 /usr/bin/ld: Undefined symbols:
_av_free
_av_freep
etc..

This is the latest svn checkout of fmpeg compiled and installed striaght.

Solution is to inlude libavutil, which has the relevant calls (in mem.o)
 (./configure LIBS='-lavutil' )

2. Compiling gets the following error...
