Linking fails under Mac OS X 10.7.2

Changed Makefile:
$(CC) -shared -Wl,-soname,$(LIB_NAME) -o lib/$(LIB_NAME) $(LIBOBJS)
to be:
$(CC) -shared -Wl,-dylib_install_name,$(LIB_NAME) -o lib/$(LIB_NAME) $(LIBOBJS)

While running 'make' it gives:

I suppose there is something to be added for Makefile to make shared library (tre) to be loaded?

Thanks for trying it out! What version of cc does this version of OSX use? (Is this gcc by the way, or the llvm version?)

Thanks for improving libcrm114 :) I found out following:
$ cc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)
