It is really intriguing -- compilation now works fine (using also ffmpeg
SVN-13767, but SCons is the same as a few weeks ago, when it didn't
work)!
For me, it means that the SCons method is not reliable at all, I've
never had such problems with make/autoconf. In fact, I even succeeded to
compile dvbcut when SCons was not working, but I had to edit heavily the
SConstruct file. Namely, I had to comment out the second line and the
'else:' statement from this block below and deindent the 'env.Append...'
lines after them (all of this in order to get the right -I flags which
were not added to the compilation line):

With all these changes dvbcut compiled fine, but I still don't
know why it didn't without and more importantly why it does now.
As I'm using Debian testing, some packages were upgraded in the
meantime, maybe one of them had such an effect.
In short, I don't like SCons :)
