I've built the AVR toolchain from scratch a number of times and also  
have a set of ports files for MacPorts that successfully builds.  I've  
never encountered a situation where avr-gcc needed the headers from  
avr-libc.  What languages are you asking avr-gcc to build?  I only  
build c and c++.  It may require the headers if you try to build java,  
fortran, etc.  The gcc configure command for my ports looks like:

configure --prefix=/opt/local --infodir=/opt/local/share/info -- 
mandir=/opt/local/share/man --target=avr --program-prefix=avr --with- 
included-gettext --enable-obsolete --with-gxx-include-dir=/opt/local/ 
avr/include/c++/4.3.2 --enable-languages="c,c++"
