Error al intentar instalar fuse-ext2 con Homebrew

Ya he instalado Homebrew y Xcode (MacOS 10.15.3). Estoy tratando de instalar fuse-ext2 para tener acceso a mis discos ext4. Creo que estoy cerca de conseguirlo siguiendo esto de https://libraries.io/github/alperakcan/fuse-ext2

$ brew install e2fsprogs m4 automake autoconf libtool
$ git clone https://github.com/alperakcan/fuse-ext2.git
$ cd fuse-ext2
$ ./autogen.sh
$ CFLAGS="-idirafter/$(brew --prefix e2fsprogs)/include -idirafter/usr/local/include/osxfuse" LDFLAGS="-L$(brew --prefix e2fsprogs)/lib" ./configure
$ make 
$ sudo make install

Pero la ejecución de 'make' genera varios errores:

/Library/Developer/CommandLineTools/usr/bin/make  all-recursive
Making all in fuse-ext2
make[2]: Nothing to be done for `all'.
Making all in tools
Making all in macosx
( cd ../../tools/macosx/prefpane; \
      xcodebuild; \
    )
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
make[3]: *** [prefpane] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

¿Qué falta en este momento?
