ponyc: Error "ld: library not found for -lSystem" on macOS Big Sur

Hi, I’m trying to compile a “Hello World” program on macOs Big Sur 11.0.1 (20B29)

$ ponyc --version
0.38.1-bba16525 [release]
Compiled with: LLVM 9.0.1 -- AppleClang-11.0.3.11030032-x86_64
Defaults: pic=true

but linking fails

Writing ./helloworld.o
Linking ./helloworld
ld: library not found for -lSystem
Error:
unable to link: ld -execute -no_pie -arch x86_64 -macosx_version_min 10.12 -o ./helloworld ./helloworld.o -L"[..]/ponyup/ponyc-release-0.38.1-x86_64-darwin/bin/" -L"[..]/ponyup/ponyc-release-0.38.1-x86_64-darwin/bin/../lib/x86-64" -L"[..]/ponyup/ponyc-release-0.38.1-x86_64-darwin/bin/../packages" -L"/usr/local/lib"  -lponyrt -lSystem

Sorry if this is an FAQ… I literally tried pony for the very first time today, so please bear with me…

Thanks for your help!

@v-almonacid Apple apparently had the ingenuous idea to delete the command line tools with every XCode update, but you should be able to make them reappear with xcode-select --install. At least that brought them (and thus /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/) back for me after the last update. Have you tried that?
