--------------------+-----------------------------
 py37-pyobjc-cocoa fails to build on my system. It gives an error message
 similar to
 [https://trac.macports.org/ticket/59425 ticket 59425], but the cause its
 slightly different.
 Error message:
 {{{

 os.path.basename(data)[6:-4].split('.')))))

 }}}

 The variable {{{data}}} in this statement is the SDK root, obtained by the
 command
 {{{
 /usr/bin/xcrun -sdk macosx --show-sdk-path
 }}}
 It appears inside the setup script this generates
 {{{
 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
 }}}
 i.e. without a version number to be extracted, whereas in a terminal
 session it generates:
 {{{
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
 }}}
 In the py-pyobjc port it uses {{{get_sdk_level(self.sdk_root)}}} to get
 the version numbers and this works correctly with commit a8e89f36dd6.
 However the corresponding commit b6d4b3fe8aa doesn't solve the problem for
 py-pyobjc-cocoa.
