[Xastir] libtiff / geotiff install hiccup

[T Wegner]

Following these instructions for installing geotiff prior to  
installing Xastir on my Powerbook g4 osx 10.5.8 macintosh:

1)   tar -xvzf libgeotiff-1.3.0
2)   cd libgeotiff-1.3.0
3)   ./configure --prefix=/usr/local
4)   make
5)   sudo make install
6)   sudo ranlib /usr/local/lib/libgeotiff.a

Following step 3, I get this error message:

checking for TIFFOpen in -ltiff... no
configure: error: You will need to substantially rewrite libxtiff to
build libgeotiff without libtiff


I looked at the Xastir install page and searched both the libtiff and  
Xastir archives, and while I did encounter what appears to be the same  
error message in a thread on the latter, I am unable to make sense of  
what I should do in my situation.

I did not donwload libtiff, but several libtiff items are found in  
searching the computer (in gui mode - I have no idea how to find files  
in command line), creation dates match the day I downloaded/installed:  
the developer tools, X11, MacPorts, and presumably using MacPorts :  
imagemagick, openmotif, pcre, db42, lcms, proj, gdal, libpng, and  
libxml2. Finally, using the internet, shapelib-1.2.10 and geotiff 1.3.0

My understanding of command line, if it isn't overtly obvious already,  
is quite limited.

Any ideas?

And be honest with me, if you think I'm getting in over my head before  
I even try using the software, maybe I should just stick with the gui  
stuff and wait for someone to develop a pre-compiled version?
