[maemo-developers] no such file or directory?

[From: mohamed ismael]

i added the following line in my code
#include <libprofile.h>
and i get the error
no such file or directory
i am using esbox IDE and
i installed the libprofile on my scratchbox using the following command
apt-get install libprofile-dev and it is installed successfully
but when i try to install it in the ordinary terminal it says could not 
find it
what is the problem?
thanks
