[Geotiff] Re: libgeotiff.so requiring libtiff.so.3

[Dan Homerick]

A correction: I did get errors using the static version of libgeotiff.a,
they were just delayed until I tried to compile a version of my program
using a few geotiff library calls.

Also, as expected, installing version 3.6.1 of libtiff and configuring
libgeotiff to use it solved all the problems.
