GRASS GIS on Mac OS X

libgeotiff version: 1.2.2
remotesensing.org

NOTE: while it may change in future versions, the patches needed are extensive enough that they will be provided in patch files. They are only for this version of libgeotiff.

In a Terminal type:

$ cd path_to_folder_containing_geotiff_source.tar.gz
$ tar -zxf libgeotiff-1.2.2.tar.gz

Grab these patches. Unzip them into the geotiff source folder (make sure they aren't in a subfolder after unzipping). Note: these are made for geotiff 1.2.2, and fix Mac OS X dynamic library building.

Then continue:

$ cd libgeotiff-1.2.2
$ patch Makefile.in makefile.in.patch
$ patch configure configure.patch
$ ./configure --mandir=/usr/local/share/man --with-libtiff=/usr/local --with-jpeg=/usr/local --with-zip=/usr --with-proj=/usr/local
$ make
$ sudo make install

Note: you will probably see a warning at the end of the make step about a missing directory, don't worry, nothing is wrong.
