Comment:

 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.
