Ah, after looking at the source code and package dependencies I found that the build scripts require GtkSpell 3.0 or GtkSpell 2.0 but the Ubuntu package depends on GtkSpell 2.0. From the site of GtkSpell I read that between 2.0 and 3.0 the API has changed. Perhaps this is the reason that it doesn't work an other problems arise, such as not finding Hunspell behind Enchant.
