Evan: Sometime next week probably, If you have svn installed, you can 
get the latest version that way.

Thank you Jeff. Setting LD_LIBRARY_PATH works fine as a quick test, though
that leads me to the "ImportError: No module named pkg_resources" problem
that the other recent posters had. I'll either try setuptools or wait for
0.9.9 to come out - will it be long?

Evan: I think this is a LD_LIBRARY_PATH problem. There are two 
possible workarounds:
1) set the LD_LIBRARY_PATH environment variable to include 
/usr/local/lib, i.e.
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
2) edit setup.py and make the following change
currents_nbp:(basemap_svn)$ svn diff
Index: setup.py
===================================================================
--- setup.py (revision 4791)
+++ setup.py (working copy)
@@ -90,7 +90,11 @@
extensions.append(Extension("matplotlib.toolkits.basemap._geod",deps+['src/_geod.c'],include_dirs 
= ['src'],))
 # for some reason, pickling won't work if this extension is installed
 # as "matplotlib.toolkits.basemap._geos"
-extensions.append(Extension("_geos",['src/_geos.c'],library_dirs=geos_library_dirs,include_dirs=geos_include_dirs,libraries=['geos_c','geos'])) 
+extensions.append(Extension("_geos",['src/_geos.c'],
+ library_dirs=geos_library_dirs,
+ runtime_library_dirs=geos_library_dirs,
+ include_dirs=geos_include_dirs,
+ libraries=['geos_c','geos']))
then rebuild. As Eric Firing pointed out to me, adding 
runtime_library_dirs negates the need to set LD_LIBRARY_PATH manually. 
This is already done in svn, and so 0.9.9 will not require manually 
setting LD_LIBRARY_PATH.
HTH,

Hi Johann,
I believe the scipy optimization package gives a variety of 
optimization algorithms but you would have to implement your own 
codes to fix/thaw parameters. That being said, there is a lot there 
and I haven't dug into all of it into detail. I would suggest posting 
a message to the scipy mailing list after the holidays and you may 
get a better response.
Cheers,
Jessica

Hi all,
Just updated basemap from 0.9.4 to 0.9.8 on Mandriva Linux 2008. I also
installed basemap-data-fullres-0.9.7. I've noticed there's a couple of
recent posts about problems (on Macs) with 0.9.8, the solution being to
install setuptools until 0.9.9 comes along; the problem I have is similar to
the posts but not the same, so I'd like to check here before proceeding with
setuptools.
I installed the included geos-2.2.3, then basemap-0.9.8, then
basemap-data-fullres-0.9.7. However when I now import basemap I get:
In [1]: from matplotlib.toolkits.basemap import Basemap
---------------------------------------------------------------------------
<type 'exceptions.ImportError'> Traceback (most recent call last)
/home/emason/python/tools/<ipython console> in <module>()

<module>()
----> 1 from basemap import __doc__, __version__
 2 from basemap import *
/usr/lib/python2.5/site-packages/matplotlib/toolkits/basemap/basemap.py in
<module>()
 29 from matplotlib.cbook import is_scalar, dedent
 30 from shapelib import ShapeFile

 32
 33 # basemap data files now installed in
lib/matplotlib/toolkits/basemap/data
<type 'exceptions.ImportError'>: libgeos_c.so.1: cannot open shared object

Yet the file, in fact a link, libgeos_c.so.1, does exist at the location
(/usr/local/lib) where it is supposed to be:
[root@msasa lib]# ll

I'd appreciate any help with this.
Thanks, Evan
