 I am generating the PortIndex on linux using the following command

 `portindex -p macosx_19_i386`

 But for certain ports, I am getting issues related to sysctl


 {{{

 one

 Another type of errors encountered are:


 {{{

 }}}


 I am running MacPorts using a Docker container on Ubuntu 20.0.4. The build
 was done using latest source code from macports-base repo.
