This looks like what happens if you try to use the latest dmd release
with an old version of Phobos, perhaps installed along with gdc.

Whoever's doing the .deb packaging really should add a versioned
Depends: field to debian/control so that it will require installation of
the correct version of Phobos, or, at the very least, refuse to install
if such is not available.

Yeah, if it's an outdated package, then it's kinda moot. (Though we
really should remove outdated packages where we can, they can kinda
become a fly in the soup sometimes.)
