Tom is attempting to install libgeotiff from source, so the recommendation
to install packages is off the mark.

The libgeotiff install process installs both the libraries and header files.

The issue is that configure is probably not looking in /usr/local/ for anything
unless you've told it to.

Please try this configure line:

./configure --prefix=/usr/local/ CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"

On linux systems packages are installed into /usr instead of /usr/local, so
this is usually not necessary unless you've got hand-installed code.

There are some conditions that can force these CPP and LD flags to be
used without manually specifying them, but they're obviously not happening
in your case.  Among those conditions are running with GDAL, whose "gdal-config"
program will usually force /usr/local into your flags variables when it's
run by configure.  I think a few other "*-config" programs that Xastir's
configure script runs can do that, too, which is why those on Linux systems
rarely run into this.

As a BSD user, where all third-party packages are always installed into 
/usr/local instead of polluting the base-system directories /usr/lib and 
/usr/include, adding those CPPFLAGS and LDFLAGS is almost second nature
when running configure.  

Give it a shot.  I bet you'll find that it satisfies in your case, too.
