Fink on macOS Big Sur(unsuccessful trial) resent 2nd

1) According to https://www.finkproject.org/index.php?phpLang=en <https://www.finkproject.org/index.php?phpLang=en>
we do not have any "official fink releases" after macOS Big Sur, though it was noticed that it would be released soon.

2) Someone at github.com <http://github.com/> and others suggests that we shall take the next guided steps.  
I have tried it, but unsuccessful. It would be helpful to teach me how to cope with it.

Before reporting any errors, please run "fink selfupdate" and try again.
Also try using "fink configure" to set your maximum build jobs to 1 and
attempt to build the package again.
If you continue to have issues, please check to see if the FAQ on Fink's
