Attention! On Mac OS, /usr/bin/libtool is not GNU libtool but rather a
helper script that is called internally when creating a shared
library. Your build log clearly shows that ../libtool (i.e. GNU
libtool) is called to link the library. The compiler, i.e. g95, then
calls /usr/bin/libtool internally. The point where it breaks is that
your /usr/bin/libtool does not understand the -force_load parameter,
which was introduced as " -Wl,-force_load,../f90/.libs/libnetcdff90.a"
in the compiler command line.

As discussed on this very list, in
http://www.mail-archive.com/address@hidden/msg04867.html, the
-force_load linker flag is only supported on Mac OS 10.6 and up.

HTH.
