/Volumes/Debian/Users/bertin/.local-109/share/mime/:/opt/local/share/mime/

(/Volumes/Debian is my -historically named- case-sensitive partition; ~/.local points to the .local-109 directory.)

A random sample of a cmake invocation:

Search the digikam source, I see it does reference XDG env. variables (haven't checked in what manner), but I also see a reference to QDesktopServices in relation to XDG specs in the ChangeLog. Could it be that Qt and KDE applications use that class? (Except that the qt4-mac port doesn't seem to patch qdesktopservices_mac.cpp ...)
