 I recently upgraded to MacOS BigSur. After the upgrade was completed I
 tried to install the new MacPorts with the pkg installer for BigSur.

 When I try to install ports I get errors.

 }}}

 When I look at the config.log, I have the following:

 {{{
 configure:5847: /usr/bin/clang
 -isysroot/Library/Developer/CommandLineTools/SDKs
 /MacOSX.sdk -c conftest.c >&5
 clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.0'
 }}}

 I have attached the config.log to the ticket. I can provide other details
 as needed. Additionally I keep on seeing this warning

 {{{

 build correctly.
 Warning: You can install it as part of the Xcode Command Line Tools
 package by running `xcode-select --install'.
 }}}

 Not sure if these are related, but xcode-select --install tells me that it
 is already installed.

 I have finally tried an
 [https://guide.macports.org/chunked/installing.macports.uninstalling.html
 uninstall], followed by an [https://www.macports.org/install.php install]
