Comment:

 This was not a clean build attempt. Please
 [https://guide.macports.org/chunked/project.html#project.tickets clean and
 try again].

 The error comes from a boost header, but unistd.h is a standard system
 header and it should be in /usr/include. If it isn't, perhaps you haven't
 installed Xcode and the Xcode command line tools. Both are required for
 MacPorts.
