[ADOL-C] Trouble building on OSX

[Dominique Orban]

Hello,

I am having difficulties building ADOL-C 2.2.1 on OSX 10.6.8 with the
--enable-sparse option. I have:

colpack 1.0.4
autoconf 2.68
automake 1.11

I issue the commands:

./configure --enable-sparse --prefix=...
make install

and this results in:

configure.ac:43: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:44: error: possibly undefined macro: AC_PROG_LIBTOOL
make: *** [configure] Error 1

I see on the web that on Linux machines, similar errors are resolved
by installing GNU Libtool. However, OSX already ships with a tool
named "libtool" located in /usr/bin (I am not entirely sure it is
related to the GNU libtool though it serves similar purposes).

Any help would be very appreciated.

Thanks in advance.
