[GRASS-dev] running d.mon outside grass shell with php & granting rights problem

[Paulick Consult]

Dear list, 

when running d.mon out of a php script, I see 

d.mon start=PNG:
/usr/local/grass-6.1.cvs/driver/PNG: error while loading shared libraries: 
libgrass_driver.so: cannot open shared object file: No such file or 
directory 

Inside the grass shell, it works fine. The environment variables for PATH 
and GRASS_LD_LIBRARY_PATH are pointing at the right locations (from my point 
of view; the requested files ar there and accessible). I nicked the php code 
from Markus'  grass.itc.it/spearfish example. 

Second thing:
I can't get outside-shell-access to a mapset even when calling in advance 
g.access with grant for both user and group. When chowning the entire 
location directory to user www-data, it works, but then there is no longer 
access from the grass shell. 

Now I'm stuck and confused. r.out.png works with the chowned directory. Did 
I mix something up with the environment variables?
