Hi,
      I tried building libtool on Mac OS X 10.7.2 with Xcode 4.2.1 llvm-gcc
compiler, and got a bunch of errors for the test suites.

Here is the procedure that I followed to build it.

Step 01.00: Install GNU libtool.


Step 01.01: Download libtool 2.4.2


To build from sources using the git repository


$ git clone git://git.savannah.gnu.org/libtool.git

$ cd libtool

$ ./bootstrap

$ ./configure CC='/usr/bin/llvm-gcc-4.2' CPP='/usr/bin/llvm-cpp-4.2'
CXX='/usr/bin/llvm-g++-4.2' CXXCPP='/usr/bin/llvm-cpp-4.2' CFLAGS='-arch
i386 -arch x86_64' CPPFLAGS='-arch i386 -arch x86_64' CXXFLAGS='-arch i386
-arch x86_64' LDFLAGS='-arch i386 -arch x86_64'
--disable-dependency-tracking


$ make -j 6

$ make -j 6 check-local
