Impossible to install Digikam Port

[bernard.meunier@…]

MacOS 10.9.2 Xcode 5.1.1 Digikam : Digital photo management program to import, organize, enhance, search and export your digital images. I try to install digikam by :

sudo port install -v digikam +debug

First I receive that : ---> Computing dependencies for digikam

But very quickly I receive these informations :

Error: active_variants: Error: invalid port depspec 'path:lib/pkgconfig/cairo.pc:cairo' Error: expecting either: port or (bin:lib:path):foo:port

What's mean ? What can I do ?

Thank a lot for any help.
