TDE strict dependency on binutils in Debian Jessie/Wheezy

HI there, is anybody aware of any good reason why tdelibs14-trinity and some other packages have a very strict dependency on binutils in Debian Jessie and Wheezy (and I suspect also on previous versions and in Ubuntu, even though I didn't check)? For example I get dependencies such as: binutils (>= 2.23.52.20130828), binutils (<< 2.23.52.20130829). The problem with such kind of dependency is that when binutils is updated, I need to do a full rebuild of TDE before I can update the binutils package on my machine. After the full rebuild is completed, everything can be updated, but I don't see the reason for having the '<<' part of the dependency since it doesn't seem to affect anything: TDE builds with both the old and the new binutils package. So I am wondering if such strict dependency is intentional or if it is something that we are dragging along from the past (perhaps because of a broken or incompatible binutils version in the past). If there isn't any particular reason, I will open a bug report in a few days about this point. Thanks   Michele
