Installing wine with osxwinebuilder I try to install wine with osxwinebuilder. When I do, I get the following error:

but cannot compile and link against it.

could not run configure command './configure --prefix=/Users/scott/wine/wine-1.5.16 --enable-shared=yes --enable-static=no --with-libexif=auto' in /Users/scott/wine/build/libgphoto2-2.4.14 - exiting


I am confused as what I should do. I have homebrew installed - should I install anything?
I will hazard the guess that you need to install libtool.  You can do that with

brew install libtool
brew link libtool


From what I understand, libltdl is provided with that.

I don't actually use homebrew so I hope that my stab in the dark helps you find your solution!
