 I encountered a failing encfs build on big sur (other ports like e.g.
 xclock nicely build and install):

 checking the logs provides:

 {{{

 The output was:

 }}}

 A **workaround** I found:

 - go into the build directory:
  {{{cd
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_fuse_encfs/encfs/work/build}}}
 - and run command {{{cmake}}}
 - then {{{make}}}
 - then {{{make install}}}
 - worked for me, I have a working encfs now ;-)
