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.
