Thank you very much, Bill, you're right :

[jm@localhost Pari]$ ldd ./premier
       linux-gate.so.1 =>  (0xffffe000)
       libpari.so.2 => not found
       libm.so.6 => /lib/i686/libm.so.6 (0xb7f60000)
       libc.so.6 => /lib/i686/libc.so.6 (0xb7e20000)
       /lib/ld-linux.so.2 (0xb7f9f000)

So, I just add your line export LD_LIBRARY_PATH=/usr/local/lib  in my 
.bash_profile and now, all is OK.

Thank you !

JM
