pkgsrc on Mac OS X
From Wikistix
Xcode
First, you will need Xcode installed, including the command-line tools, else you'll likely get the following error:
bash$ bmake replace
ERROR: This package has set PKG_FAIL_REASON:
ERROR: No suitable Xcode SDK or Command Line Tools installed.
*** Error code 1
Install the command-line tools:
bash$ xcode-select --install
xcode-select: note: install requested for command line developer tools
If you still get the above error, run the following from pkgsrc which may provide information (as it did here):
bash$ /usr/bin/xcrun --sdk macosx$(sw_vers -productVersion) --show-sdk-path
xcodebuild: error: SDK "macosx10.15.3" cannot be located.
xcodebuild: error: SDK "macosx10.15.3" cannot be located.
xcrun: error: unable to lookup item 'Path' in SDK 'macosx10.15.3'
Further, it appeared the default wasn't installed correctly?
bash$ xcrun --show-sdk-version
xcodebuild: error: SDK "/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk" cannot be located.
xcrun: error: unable to lookup item 'SDKVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk'
bash$ ls -l /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk

"Fixed" by manually adding to mk.conf:
OSX_SDK_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
