error while loading shared libraries 

Hello !

Always using gp-pari in gp-mode, I now need to use it in library mode.

With a simple C program premier.c and the classical Makefile :

CC = cc
INCDIR = /usr/local/include/pari
LIBDIR = /usr/local/lib
CFLAGS = -O -I$(INCDIR)  -L$(LIBDIR)

all:    premier

premier:        premier.c
      $(CC) $(CFLAGS) -o premier premier.c -lpari -lm



the compilation step is OK :


[jm@localhost Pari]$ make
cc -O -I/usr/local/include/pari -L/usr/local/lib -o premier premier.c -lpari -lm 
[jm@localhost Pari]$

But after that, I get :

[jm@localhost Pari]$ ./premier
./premier: error while loading shared libraries: libpari.so.2: cannot open shared object file: No such file or directory
Well, I installed Pari with ./Configure --> make --> make install and all seemed OK.
In another PC (under Linux Mandriva 2008.0), I also tried an installation with urpmi 

[root@kbamur ~]# urpmi pari

Does anyone know what arrives ?

Thank you for advance,
