I never installed Flame or Edit World (wiki) but think that is important to the future of the project .
So I think (but I'm not a programming user) maybe for Linux users there are a software that can be used to do front-end for this task - Gambas →
http://gambas.sourceforge.net/This IDE is siimilar to Visual Basic and Java , maybe someone can do a good editor with this and then for Linux users finally have a native program to build maps.
