[Mono-list] Problems to get ZedGraph working, apache mod_mono, ok with xsp2

[David Temes]

That is exactly what was hapening, first test i have done is runing apache 
directly (apache2ctl start) as root with the same environment i am running 
xsp2 and surprise surprise,  it works!!! , then launching apache through the 
init script fails (/etc/init.d/apache2 start) . I tryed to figure out what 
env settings are missing when running from the init script but have come to 
a simpler solution, editting the /etc/lf.so.cong, that now looks like this 
in my machine:

/usr/X11R6/lib
/opt/mono/lib
/usr/local/lib

and then of course running ldconfig

It seems that putting the mono libs there has done the trick, i do not know 
if order matters but just in case I put it before /usr/local/lib.

Thanks and regards

David Temes.
