According to
https://github.com/macports/macports-ports/commit/5c48aa5a22139aedc616ff5ee173f9ca021580e0
support for Mac OS X 10.5 and earlier was removed in libvpx 1.5.0, so
you
would need to build an earlier version than that.

I can attempt that, however, also to debug the integrated libvpx of
TTF/Firefox, I downloaded 1.5 and also latest 1.6.1
I am able to build "off tree" by using the macports clang compiler
latest libvpx 1.6.1
CC=clang-mp-3.4 CXX=clang++-mp-3.4 ./configure
Builds happily. I tired the testsuite which did take hefty 7h 30' to
run and downloaded several gigabytes

Maybe this is acceptable? I don't know how it fares on 10.6 and up,
this is a 32bit build.
What compiler is the port using? Maybe PPC would fail, but intel
builds.
I also tried compiling even 1.5 with gcc 4.8 and gcc 6, but it fails
the same way the integrated libvpx of TTF fail.
I looked int othe code and it fails with assembler issues, the
original coder noted that it is for gcc 4.7 and clang 3.4 up, so it
should work!
Apparenltly the issue is that our MP cc uses an "old" linker that
doesn't support those instrucions, there are several posts around. Are
we?
