Comment (by bal-agates):

 I saw there was an update to the OpenBLAS port so I upgraded all my ports
 and then tried to install py311-scipy.  On my system the build of
 py311-scipy still fails in the same way.

 I think the ultimate problem is library libopenblas-r1.dylib contains two
 references to /opt/local/lib/libgcc.  This is an error but apparently most
 older linkers ignored it.  Apparently the Xcode 15.0.X linker treats this
 as an error.  Chris Jones suggested that the Xcode 15.1 linker might solve
 the issue.  Xcode 15.1 hasn't been released yet but I did see "Xcode 15.1
 beta 3" was released on 14-Nov-2023 so it probably is getting close to
 being released.

 I have not studied the OpenBLAS port as to why there are two references to
 /opt/local/lib/libgcc.  It might be as simple as one reference comes from
 being manually specified and another auto-generated by cmake?  I have a
 poor understanding of cmake and what triggers it to do things.  Are there
 any port maintainers for OpenBLAS on this Issues distribution?

 The only short term workaround I can think of is to manually remove the
 duplicate reference from libopenblas-r1.dylib.  Mark Mentovai commented
 above that he did this and it fixed the problem.  Not sure what command he
 used.  Later on Ken (above) did the same and it fixed the problem.  Ken
 listed the command he used.
