I built from outside the source tree and used: /home/bfriesen/src/graphics/libtiff/configure 'CC=gcc-4.3.2 -m64' 'CXX=c++-4.3.2 -m64' '--enable-shared' '--prefix=/usr/local64' This is with a GCC 4.3.2 I installed myself from source code. Removing the -4.3.2 from CC and CXX as well as changing the prefix to your own preference should do the trick. However, I am not sure that I would recommend v3.8.2 due to many bugs.
