Problem running a test program

Hi
 
I have successfully installed comedi 0.7.67 with the comedilib 0.7.20 on Red Hat 9.0. But i have a problem in running the example program tut1.c on NI 6025E dio card. The program compiles correctly but when i try to run, it gives the following message:
"error while loading shared libraries: libcomedi.so.0: cannot open shared object file: No such 
file or directory"
 
The complete log is given below:
 
[root_at_localhost comedi]# cc tut2.c -lcomedi -o tut2
[root_at_localhost comedi]# ./tut2
./tut2: error while loading shared libraries: libcomedi.so.0: cannot open shared object file: No such file or directory
