The relevant error in the log seems to be:
:info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_print_freetype/freetype/work/freetype-2.4.8/include/freetype/config/ftstdlib.h:168:10: fatal error: 'stdarg.h' file not found
I will assign the ticket to myself because I am the maintainer of freetype, but I do not know what to do to fix the problem.
Does the file stdarg.h exist anywhere on your system? For example /usr/include/stdarg.h? My understanding is that it should exist, and it does on my Snow Leopard system. Because the log you've attached is incomplete, it doesn't show what OS version you have. Please "sudo port clean freetype" and try again and attach the new complete main.log so that we have a complete record of what's happening. Also please indicate your OS and Xcode versions.
We've had some other reports of errors with stdarg.h, including #26804 and #33306, but they seem unrelated to me, since your message does not implicate an SDK. The latter ticket suggests a bad Xcode install was responsible; you could try uninstalling and reinstalling Xcode.
