Yes but  libtool is too "GNU tool  oriented", as an example  it does not
support nasm, which is important on the IA32 platform.

Please  use  compat=2  version=1,  2.1   is  the  API  version  used  in
xvidcore-0.9.1.  That's  what   i'm  using  in  the  release-0_9_1-fixes
branch. It  would be cool if  you had a look  at that branch  as I fixed
some build bugs in it.

Basically I've been missing these 3 options:
 -compatibility_version
 -current_version
 -install_name

They will be added in configure.in:
[...]
     darwin*|raphsody*)
     AC_MSG_RESULT([-dynamiclib -flat_namespace])
     STATIC_LIB="libxvidcore.\$(API_MAJOR).\$(STATIC_EXTENSION)"
     SHARED_LIB="libxvidcore.\$(SHARED_EXTENSION)"
     SPECIFIC_LDFLAGS="-dynamiclib -compatibility_version \$(API_MAJOR) -current_version \$(API_MINOR) -install_name \$(libdir)/\$(SHARED_LIB) -flat_namespace"
     SPECIFIC_CFLAGS="-fPIC -fno-common -no-cpp-precomp"
[...]


Please test that on the release-0_9_1-fixes branch, if it's good then it
will be commited.

Another question:
On GNU/Linux systems,  we don't have to do  the symlink because ldconfig
will do it for us. Is the symlink really needed on MacOSX ?
