Blender quits when trying to render from command line

hi,

i’m trying to render a scene in the background by launching blender with the -b option from the command line. blender quits immidiately. i’m on a mac with os x 10.4, python 2.4.1, blender 2.41.

localhost:~ user$ blender -b scene.blend
Using Python version 2.4

Unable to load: libtiff.
Try setting the BF_TIFF_LIB environment variable if you want this support.
Example: setenv BF_TIFF_LIB /usr/lib/libtiff.so

Blender quit

This happens to me sometime because I haven’t set something correctly…will it rendering in Blender? If so, post the blend file and I’ll see if I can render it.
