libvpx on 10.5 and earlier

[Riccardo Mottola]

Hi,

I have big issues building TenFourFox currently because of its 
integrated libvpx, I haveissues with sse2/sse3 and yasm.
If anybody is a bit knowledgeable there.... the TTF-PPC uses different 
files so it works, Mr. Kaiser worked essentially in porting libvpx to 
PPC and 10.4

Another (temporary) option would be to use the system libvpx (mozbuild 
offsers an attribute for that), this would me allow to continue working 
on TTF and check what other issues there are, I did not find a way yet 
to build without libvpx support, I found no options.

However if I attempt to install  it I get "1.6.1 does not build on Mac 
OS X 10.5 Leopard or earlier"
Could it be feasible to get it building on Intel? or did an earlier 
version build. can I ask port to buiild specifically an older one?
