 OS: BigSur Version 11.5.2

 1. Initially tried binary port of geda-gaf and when I use the gnetlist
                  gnetlist -g spice-db sample.net sample.sch
    import xorn.storage fails with unresolved symbols.

 This is an error.  Please report it to bug-xorn at hedmen.org

 2. Closer examination of shared object library with 'otool -L ' did
 confirm that the symbol was
    indeed undefined.

 3. Deleted geda-gaf binary port and tried with source port. Source
 compiled and installed well,
    but the problem persists. (source compiled with   mp-clang-9.0,
 python27 )
 4. WORKAROUND:  Make the following change to Makefile in  geda-
 gaf-1.10.2/xorn
 {{{
         Replace.  libxornstorage_la_LDFLAGS = -export-symbols-regex
 '^xorn_'
         With      libxornstorage_la_LDFLAGS =
