Comment (by MurrayDaw):

 Thank you for the quick response.

 I read what you wrote and also followed the link you sent. I think you’re
 telling me to apply the patch to mpich-gcc10 and any other
 port that generates a similar error. I followed another link and found the
 file
 dynamic_lookup-11.patch
 that I think can be used for this but I’m unsure about how to do that. Or
 maybe that isn’t correct.

 Can you send me to instructions on what the next step should be?

 Also, if I don't get an error during  build of some port does that mean
 this libtools problem does not affect that particular port?
