Building this package today (and for several weeks now) has been blocked by libinsighttoolkit4-dev being not installable in sid. There seems to be no bug report against libinsighttoolkit4-dev so so .. As aptitude tells me
The following packages have unmet dependencies: libstdc++6 : Breaks: libinsighttoolkit4.7 (<= 4.7.2-2) but 4.7.2-2 is to be installed. does anyone have knowledge about how to fix the issue between libstdc++6 and libinsighttoolkit? I'll try something myself and after failure file a bug report against libinsighttoolkit.. -- Antti Järvinen
