Comment (by macports2@…):

 As you suggested, the Xcode command line tools had not been installed
 (oops, I thought they were).

 After installing the command line tools I successfully built graphite2 and
 the puTTY distribution, and was able successfully launch puTTY after
 installing XQuartz.

 Thank you very much for your help.
