  py39-docutils has the following notes:
    To make the Python 3.9 version of docutils the one that is run when you
    execute the commands without a version suffix, e.g. 'rst2man', run:
    
    port select --set docutils py39-docutils

What I've learned is:

• ___sincos_stret is emitted by the compiler when a program wants both sin(x) and cos(x) since it is faster to compute both at once and that's what ___sincos_stret does
• ___sincos_stret was added in OS X 10.9 so since you are on 10.7 it shouldn't be getting used
• the build is using -mmacosx-version-min=10.13 to indicate that 10.13 is the minimum OS version it wants to be supported, which explains why ___sincos_stret is being used, but probably also means the port doesn't actually work on OS versions earlier than 10.13 at the moment.

I probably just need to find wherever this 10.13 minimum is being set and remove it. However it's possible there is a good reason why the developers set it.

Thanks,

not so long ago (maybe 3-4 months probably) was able to install a working version of mpv via macports comfortably on a computer running mountain lion. is it possible to press a "button" to install this "version" instead of the latest and newest that doesnt seem to build on older iterations of mac os x any longer§? sorry for my request, but i have grown fond of installing software by simply typing a few words into a terminal window.

The problem with rubberband will be solved, I think, once I push a commit which is part of a batch of other work that I'm not done with yet.

To install an older port, see wiki:howto/InstallingOlderPort.

Thank you very much for your help ryandesign; attempted to use the guide to install older version, but don§t know if by design or not, it still seems try to use "rubberband-2.0.0_0.darwin_12.x86_64.tbz" which is the same as newer version of mpv tries to build? therefore it fails also for older mpv? would i have to include also manually an older version of rubberband in the equation?

So far we haven't seen any evidence of any problem with the current version of mpv. The only problem you've reported here is a problem with rubberband. But just give me a couple hours and hopefully by then I'll finish the rest of the bits and have the fix pushed.

In 7132745bc362fe40057a5edc8bbd341ffb41b363/macports-ports (master):

rubberband: Use the right deployment target

Set -mmacosx-version-min to prevent the build system from setting its
own value.

Closes: #64268

Patch the build system so it doesn't request C++14 for no reason.

Patch the build system so it doesn't add -arch flags that might be
different from the ones MacPorts wants to use.
