problems on suse 9.0

[emilio]

hi JD

first of all thanks for your help. i read your message and i have to say i 
didnt get to solve the problem. after this atempt and with the information of 
your coment i made a search in the internet and found the next text:

"Problem: Trying to run octave gives: 

appc63:/etc # octave
octave: error while loading shared libraries: liboctinterp.so: cannot open 
shared object file: No such file or directory

Solution: 
add /usr/lib/octave-2.1.49 to your /etc/ld.so.conf file then do:
/sbin/ldconfig"

and of course i tried it , but at the end i got an error when i tried to do 
ldconfig. it seems this comand does not exist on my computer (?)
