Comment:

 As with any build failure bug report, please attach the main.log file.

 See also #59417, #60246, #61371; these may all be describing the same
 underlying problem.

 /Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Security.framework/Versions/A/Headers/Security.h
 does exist on our macOS Big Sur x86_64 buildbot worker, where we have
 macOS 11.2.3 and Xcode 12.4 and the Xcode 12.4 version of the command line
 tools installed. If that file does not exist on your system, try
 reinstalling the Xcode 12.4 version of the command line tools.

 A problem may be that the credential_osxkeychain variant performs its
 building using `system` in a post-build block. This would not use the
 environment variables that MacPort sets during a normal build, including
 the SDKROOT environment variable that tells it which SDK to use, so it may
 be that this part of the build is not using the right SDK and therefore
 can't find the header.
