zlib: libtool: unrecognized option `-o'

[fastcuts@…]

Hi

I've been trying to install gphoto2 based on instructions found here: ​http://blog.dcclark.net/2009/05/how-to-gphoto-primer.html

I got an error about not being able to install Zlib.

Here is the output from the gphoto2 install try. Any ideas??

I appreciate any help. Thanks.

I suspect you have replaced /usr/bin/libtool with a copy of GNU libtool. What does "/usr/bin/libtool --version" say? If it says it's GNU libtool, then I'm right and you should restore /usr/bin/libtool to the version that Apple provides, then clean zlib and try again.
