Hello,

A little embarrassing, but I need some direction. I realize macports user 
support does not really exactly support the port I need (ffmpeg), I have a 
feeling someone reading this will know what's up from the brief details I can 
provide. Please allow me to describe my situation, and where I think I went 
wrong. 

I am running snow leopard 10.6, and while I don't expect support to continue 
forever (if it wasn't ended some time ago here and nearly everywhere, though 
last I checked Apple still sold snow leopard server software, probably while 
supplies lasted), I expected to simply stop updating and allow the tools that 
always worked to freeze at whatever version, and continue working with them as 
long as possible. 

ffmpeg and a few other ports are critical to my scripts, and I broke ffmpeg, 
and can't rev-upgrade. I went a long time without upgrading, then upgraded some 
ports and everything seemed to work, blew away previous builds. Then on a 
subsequent upgrade of I think x265, ffmpeg broke. I read about a solution, 
which was to blow away x265 and rebuild it. That didn't work, though I believe 
x265 rebuilt, ffmpeg is still broken... the error should look familiar when I 
call ffmpeg, I get


> dyld: Library not loaded: /opt/local/lib/libvpx.5.dylib
>  Referenced from: /opt/local/bin/ffmpeg
>  Reason: image not found
> Trace/BPT trap


the rebuilds for ffmpeg fail with

> Error: Failed to fetch libsdl2: Building libsdl2 @2.0.9 on Mac OS X 10.6 
> requires the MacOSX10.7.sdk to be present in /Developer/SDKs/

So my understanding, if correct, is a dependency of the next (or current) rev 
of ffmpeg requires 10.7 SDK, which is never going to be present on my snow 
leopard box.

I don't need the current build of ffmpeg. Last build that worked... was fine. I 
don't know why I messed with it, but if I can get a working build, I'll just 
freeze my system and stop upgrading the ports. I would just restore a backup, 
but I've never restored a Time Machine back up of my system, and I'm not 
entirely sure I remembed to include  /opt in the backups, and they don't appear 
to be there.

I know there is one method... involving git I believe... that I don't have 
experience with... to check out... the right version that will build completely 
on 10.6 without trying to use a dependency I can no longer build. 

I don't want to waste anyone's time with my problems. I thought there might be 
someone still running snow leopard and ffmpeg subscribed to the list. If not, I 
would be grateful for some direction or perhaps a better understanding of just 
how deep my troubles run. And probably direct contact is ok to keep this bs off 
the listserv. Sorry for the bother, but I have no where else to turn (other 
than ffmpeg support, that I'd like to keep my problems far away from). All 
olutions to my previous build issues were solved here, and I wasted some time 
before I realized I had to ask for help. Thanks for any help provided comments, 
otherwise please ignore and carry on with the outstanding work.

Respectfully,
Chilli
