Actually, I've tried compiling the latest version of libtiff using the following process:
(1) unpack tar
(2) goto main directory, "sudo make configure"
(3) sudo make install
Unfortunately, this still drops a libtiff.a file in /usr/local/lib. Grass still requires libtiff.dylib. When I copy the libtiff.a file to libtiff.dylib and run r.out.tiff in grass, I'm greeted with the following:
"dyld: r.out.tiff malformed library: libtiff.dylib (not a Mach-0 file, bad magic number
Trace/BPT trap"
So, I'm guessing that the difference between a .a and .dylib library in the mac world is more than just the filename... any ideas?

>You need to compile or install the Mac OS X version of the libtiff
package. The easiest way is to use the Fink package manager
(fink.sourceforge.net) and then link
libtiff.dylib to /usr/local/lib if you are installing precompiled GRASS
binaries, or give the configure script the location of the tiff libraries
and includes if you are compiling GRASS yourself, /sw/lib and /sw/include,
respectively if you are using fink.--
