It does: $ dpkg --compare-versions 1:7.6.4-0.4 '>=' 1:7.2d $ echo $? 0 The issue seem to lie in that there are two different packages involved: guile-2.0-libs depends on libgc1c2 (>= 1:7.2d) debfoster depends on libgc1 (>= 1:7.2d) libgc1 conflicts and replaces libgc1c2 I think guile-2.0-libs would need to be changed to depend on libgc1, but that will probably also require a rebuild, to link with the new library.
