In order to open CMYK photoshop files, I want to install the separate+ plugin for gimp. Since for building separate+ from sources it is required editing the makefile by hand(?), I was hoping for an ubuntu package. I installed gimp-plugin-registry via apt-get, which is supposed to contain separate+. After installing it, gimp has many new plugins enabled, but still doesn't have cmyk mode nor does it open cmyk psd files. In the plugin browser i can see the separate plugin (which already should have enabled cmyk image mode, no?), but not the separate+ plugin.

How can I get basic CMYK support please?

EDIT: Ubuntu-64bit system EDIT2: According to this post from 2011, even with separate+ installed opening cmyk-psd files is not possible. Does this still hold true end 2013? He lists some alternatives which all are not satisfactory.

IMHO, already it is unfortunate for linux as a platform for artists, that cmyk support is not there out of the box in gimp, but at least the installation of the plugin should be easy.

You could reference the following wiki.

CMYK support in The GIMP

Although it is ArchLinux specific, it is helpful.
