Comment (by kencu):

 MacPorts legacy support adds {{{__sincos}}} support to systems <= 10.9.

 https://github.com/macports/macports-legacy-support

 You add it to the build by editing the Portfile {{{bbedit `port file
 py39-scipy}}} and adding this near the top, at the proper place:

 {{{
 Portgroup legacysupport 1.1
 }}}

 as per this document:

 ports/blob/master/_resources/port1.0/group/legacysupport-1.1.tcl
