pb /usr/lib/libiconv.a

Hi ,

I got aix 5.1 and try to launch samba 3

i try to launch testparm  but i got this error message :

Could not load program testparm:
        Dependent module /usr/lib/libiconv.a(libiconv
        Member libiconv.so.2 is not found in archive

the file /usr/lib/libiconv.a  exists !

when i look what's inside :
# ar -v -t /usr/lib/libiconv.a
rwxr-xr-x   300/300   112890 Aug 14 01:53 2002 shr4.o
rwxr-xr-x   300/300   113076 Aug 14 01:53 2002 shr.o


has anybody an idea of the pb ?
thanks in advance.

david.
