This is my fault.. The lazarus icon changed name from version 0.9.24 and I failed to spot this. So, in the src_install part of the ebuild: dosym ../lazarus/images/mainicon.xpm /usr/share/pixmaps/lazarus.xpm should now be dosym ../lazarus/images/ide_icon48x48.png /usr/share/pixmaps/lazarus.png Feel free to ask for an updated ebuild if required.
Thanks, I hadn't noticed this either. Fixed now (without a revbump).
