Mike:  Sounds like you need to modify LD_LIBRARY_PATH to add the 
directory where you installed libgeos.

Jeff - Thanks, that seemed to solve _that_ problem.  However, after  
going through the build process (again, successfully), I get the  
following when trying to import Basemap:

from mpl_toolkits.basemap import Basemap
   File "/usr/local/epd/lib/python2.5/site-packages/mpl_toolkits/ 
basemap/__init__.py", line 43, in <module>
     import _geoslib, netcdftime
ImportError: libgeos_c.so.1: cannot open shared object file: No such  
file or directory

I had to compile geos because this version of Basemap didn't seem to  
work with the version of geos that EPD uses.  I built GEOS in a local  
home directory.  Do I need to build it in a global location (like /usr/ 
local)?

What if you edit the mak.osx file and use 10.5 for the
MACOSX_DEPLOYMENT_TARGET -- I had set it to 10.4 for building the
installers, but there is no need for that when building from src for a
local install.

What if you simply remove all references to MACOSX_DEPLOYMENT_TARGET
in the make.osx file?  Does that work for you?

Hi Ariel,

Thanks for the suggestion. Combining John's new makefile with the
changes to the Python.framework Makefile yielded:
distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET
mismatch: now "10.4" but "10.5" during configure.

As a general philosophy, I'm a bit hesitant to go about changing stuff
that's part of the Python framework directory structure. I'd be
worried about ripple effects when debugging other builds in a couple
months when I forget that I've modified it.

As I noted the other day, from a clean SVN checkout on 10.5/py 2.6,
this one-liner works:

env PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig ARCHFLAGS='-arch i386'
CFLAGS="-Os -arch i386" LDFLAGS="-Os -arch i386 -L/usr/X11R6/lib"
python setup.py install

This avoids libgcc from gfortran in /usr/local/lib and doesn't require
building anything extra. I suppose it's not portable to 2.4 and/or
10.4, though.

I'm willing to try some more builds if it would help, though it
appears I just keep uncovering problems :(
