Frankly I don't think it's worth updating this ebuild. Upstream is changing things often (for instance crossfile plugin is now merged into Quanta).
If you need some particular plugin and you know it's maintained and works well (and you also know kdevplatform version it is compatible with), tell us, it may be worth creating separate ebuild for it, like we used to have one for kdevelop-git for instance (which is now merged to kdevplatform) : http://git.overlays.gentoo.org/gitweb/?p=proj/kde.git;a=commit;h=d1f7f35b2cdb97943e25c7afab2b6964a0121aa1
Acctually i compile needed plugins like the mercurial plugin or language support from quanta's git. Okteta is the first plugin ported into kdevelop or git into kdevplatform and other will follow. I will commit my patches direct to the (k)developers. Maybe there is no need for this ebuild, so you're right Maciej. Changing bug to WONTFIX.
