Yes it is, i tried make clean && make distclean,
i also tried on a fresh svn download.
I've installed on my system different grass versions :

grass64 (binary verion)
grass65 , grass70  (from svn)

Thanks! i'm self.teached so advice like these ere for me a great help

i hope i modified it well :

def OssimImg2rr(img1):
     myenv = os.environ.copy()
     myenv['DYLD_FRAMEWORK_PATH'] = '/var/tmp/XcodeBuilds/Release'
     myenv['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
     output = subprocess.Popen(['/var/tmp/XcodeBuilds/Release/ 
img2rr' ,str(img1)], stdout=subprocess.PIPE, env = myenv).communicate()
