install problems v1.4.2 1.4.3

[Shibaji Shome]

Hi,
 I am trying to install libtool on my Mac G4 ruynning OSX 10.1.5. make
terminates with the following error:

libtool: unrecognized option `-arch_only'
Try `libtool --help' for more information.
make[1]: *** [libltdl.la] Error 1
make: *** [all-recursive] Error 1

i tried to install both libtool-1.4.2 and 1.4.3 and both terminate with
the same error. 
Will be grateful for any help on how to resolve this.
Thanks!
Regards,
Shibaji
