Instalación de Wine con osxwinebuilder

Intento instalar Wine con osxwinebuilder . Cuando lo hago, me sale el siguiente error:

...

configure: error: cannot compile and link against libltdl
libgphoto2 requires libltdl (the libtool dl* library),
but cannot compile and link against it.
Aborting.

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

Estoy confundido en cuanto a lo que debo hacer. Tengo homebrew instalado - ¿debo instalar algo?
