I'm tring to debug these weird situation ....
assured that only osx is affcted by these problems, (on linux i've no problems)
i tried to run the img2rr executable, using python inside a grass session (6.4, 6.5 & 7.0)
using a grass raster file it do not works, while using a simple geotif instead of a grass file ... it works :
GRASS 6.4.0RC3 (spearfish60):~ > export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences
GRASS 6.4.0RC3 (spearfish60):~ > ipythonPython 2.5.1 (r251:54863, Jan 13 2009, 10:26:13)
Type "copyright", "credits" or "license" for more information.

^^^ Using a GTiff file
so ... the problem is in :
export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences
inside grass - python it do not works as aspected.
here other debug :
start a new grass shell, omitting the step :
export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences
GRASS 6.4.0RC3 (spearfish60):~ > ipython
..

^^^ the same message come up in bash too, if i don't export the "OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences"
adding the export line :
In [4]: os.environ['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
In [5]: subprocess.call('/var/tmp/XcodeBuilds/Release/img2rr /Users/Shared/grassdata/spearfish60/PERMANENT/cellhd/geology', shell=True)

it give me the lib error
but ... the libs are not broken!
beacouse inside a standard python it works :
In [1]: import os
In [2]: import subprocess
In [3]: os.environ['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
In [4]: subprocess.call('/var/tmp/XcodeBuilds/Release/img2rr /Users/Shared/grassdata/spearfish60/PERMANENT/cellhd/geology', shell=True)

doing a more depth debug ....
i tried to wrote a script in grass, to avoid use of python, that is :
####################################
#!/bin/sh
#% Module
#% description: Calculates Optimum-Index-Factor table for LANDSAT TM bands 1-5, & 7
#% keywords: raster, imagery, statistics
#% End
#% option
#% key: image1
#% type: string
#% gisprompt: old,cell,raster
#% description: LANDSAT TM band 1.
#% required : yes
#% end
if [ -z "$GISBASE" ]
then
echo "You must be in GRASS GIS to run this program" >&2
exit 1
fi
if [ "$1" != "@ARGS_PARSED@" ]
then
exec g.parser "$0" "$@"
fi
eval `g.gisenv`
: ${GISBASE?} ${GISDBASE?} ${LOCATION_NAME?} ${MAPSET?}
LOCATION=$GISDBASE/$LOCATION_NAME/$MAPSET
export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences
/var/tmp/XcodeBuilds/Release/img2rr $LOCATION/cellhd/$GIS_OPT_IMAGE1
####################################
unlucky i get the same error :
GRASS 6.4.0RC3 (spearfish60):~ > i.img2rr image1=geology
MPI running with 1 processors...
ERROR: Incompatible library version for module
... at least i eliminate the python ... as the cause of my problrems 
please people help mde to know what is the problem, if exists a wok-around ... or do you know a solution ...
but ... maybe a know the answer, is these problem generated by a difference in the libs that i'm using to build ossim and grass ???
for the build i'm using the exactly same gdal.framework ... but my think is about tiff/libgeotiff files ... maybe they can be the cause?
any suggestion is really welcome!
Have you any ideas about these weird behavioure, why it happens, how to debug it ?
please tell me if you need better description, or log.
Thanks!!!
