make all fails on libpng

[Snakehand]

I am trying to fix a possible bug* in streamts, but my build fails in libpng, so I am a bit stuck at the moment *

/home/dream/dbox2/cdk/lib/gcc/powerpc-tuxbox-linux-gnu/3.4.4/../../../../powerpc-tuxbox-linux-gnu/bin/ld: cannot open linker script file libpng.vers: No such file or directory
Building on ubuntu, having installed libpng3-dev

* from streamts.c )

/* make sure to start with a ts header */
offset = sync_byte_offset(buf, TS_SIZE);

if (offset == -1)
continue;

packet_stdout(buf + offset, r - offset, NULL);

- if this bit of code actually triggers, it may not really restore sync, but rather begins truncating every 362 TS block.

Some guy by the name ridax is selling a fix for this ( http://www.ridax.se/dreambox/ at 10 euro a pop ), so rather that lecture him on the GPL, I thought I would fix this the proper way...
