Can I download newest Mac OS X-compiled mjpeg tools versions somewhere?

I'm on the mjpeg-users mailing list and I'd like to use the latest versions when submitting bug reports and asking questions.

I prefer to use MediaPipe and MissingMpegTools as GUI front-ends to mjpeg tools but AFAIK some tools in these packages are not necessarily the latest versions.

So I'd like to grab the latest mpeg2enc, mplex etc and update my copy of MediaPipe or MMT with the newest component while troubleshooting. I guess I could compile them myself but as an UNIX newbie I'd rather use a precompiled binary, if possible. Or should I just use fink?

...some examples where I have felt the need to update the GUI wrappers' UNIX components:

The current VCD Builder 1.1.1 can't add chapter points beyond 25 minutes. VCD Builder's author kindly emailed me the newer version of mpgtx which fixed this bug (I had to chmod u+x mpgtx before it worked so I almost feel like an UNIX guru

I recently had one specific input file which generated spikes in the XVCD data rate and consequently mplex frame data under-runs. Some mjpeg tools gurus speculated that the mplex version I was using in MMT has some bugs that have since been corrected (one guru speculated the error may have been caused by some known deficiencies in the mpeg2enc motion estimation PowerPC/Altivec routines, though).
