I spent a little more effort on this and using ar I find that libmjpegutils.a is listed twice in the .a file. Once at the bottom, once at the end. If I remove both of them and add libmjpegutils.a to the link line, I can get the mplex to go through with no undefined references.
However, I still get a crash out of gcc linker when I tried to build mpeg2enc. I wrote a little script to recursively figure out which .o files it needed and link that way. But I got stuck on an fdct assembly file that refers to GLOBAL_OFFSET_TABLE. So I was unable to get past resolving all symbols. My efforts to try to understand how this symbol is meant to work weren't successful. Any pointers to that aspect (in context and of a simple minded nature) would be appreciated. I think the root of the problem may lie with the configure (not that it is at fault, just that we might get better luck there). Are there some options I should try to set to cause this to build differently ? Again, any help appreciated.
