 avrdude fails at the linking stage when trying to make libavrdude.1.dylib:

 {{{
 Undefined symbols for architecture x86_64:
   "_avrdude_message", referenced from:
       _arduino_read_sig_bytes in libavrdude_la-arduino.o
       _avr_tpi_chip_erase in libavrdude_la-avr.o

 }}}

 and so on - see attached for full output.

 Building by hand works (sudo -u macports env
 CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib" ./configure &&
 sudo -u macports make in the MacPorts build directory). Looking at the
 different link lines, macports uses clang and building by hand is
 defaulting to gcc. Macports also uses -arch x86_64 twice and specifies
 -syslibroot which the successful build does not.
