 MacPorts 2.3.4

 Trying to install xymon-client. Was able to install almost all the
 dependencies for the xymon-client port, but it install graphite2 fails.

 Checking the log file, looks like it fails on this line:
 :info:build
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/__config:23:10:
 fatal error: 'unistd.h' file not found
 :info:build #include <unistd.h>
 :info:build          ^
 :info:build 1 error generated.

 Running the command `xcode-select -p` shows that I have xcode command line
 tools installed: "/Applications/Xcode.app/Contents/Developer"
 However, when running sudo port install xymon-client, it gives me a
 warning message saying that it might not be installed...

 "Warning: The Xcode Command Line Tools don't appear to be installed; most
 ports will likely fail to build.
 Warning: Install them by running `xcode-select --install'."
