This distro iso installation only supports basic and desktop installations. Although both deskpro and developer options are listed, their installation will result in an error condition. The archlinux32 distribution this is based on, has released a miriad of bits and pieces around the development environment ; so much so that ithas made it practically impossible to keep track of what versions require which library versions, etc. - these tasks are normally performed by the build team, so trying to keep up has proven futile. The package lists for deskpro and developer can be found in the file: /usr/share/calamares/modules/packages.conf. Install what you can.
