Hi, Can you try patch of https://github.com/rbenv/ruby-build/issues/1133#issuecomment-331332963 with your environment?

----------------------------------------
Bug #14089: Configure/build issue on OSX 10.12 w/ utimensat
https://bugs.ruby-lang.org/issues/14089#change-67737

----------------------------------------
For other reasons I recently installed xcode (instead of JUST using the command line developer tools). This caused builds on ruby to break. 

The symptom happens when rdoc tries to build the doco:

~~~
dyld: lazy symbol binding failed: Symbol not found: _utimensat
~~~

You can see this in the build output:

~~~
file.c:2580:13: warning: 'utimensat' is only available on macOS 10.13 or newer
      [-Wunguarded-availability-new]
        if (utimensat(AT_FDCWD, path, tsp, 0) < 0) {
            ^~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/sys/stat.h:374:5: note: 
      'utimensat' has been explicitly marked partial here
int     utimensat(int __fd, const char *__path, const struct timespec __...
        ^
file.c:2580:13: note: enclose 'utimensat' in a __builtin_available check to
      silence this warning
        if (utimensat(AT_FDCWD, path, tsp, 0) < 0) {
            ^~~~~~~~~
~~~

and the clue is that path to `MacOSX10.13.sdk`. The Xcode.app doesn't ship with 10.12, but the developer tools do. It is fixed with:

~~~
$ sudo xcode-select --switch /Library/Developer/CommandLineTools
~~~

This is here mostly for documentation / search purposes... but maybe we could do something to improve the situation by figuring out that it is being linked against the wrong SDK version?
