Indeed, there is only one gns3 package, because it is Architecture: all.

You're not doing anything wrong, you have just hit a limitation of
multiarch. An Architecture: all package is treated like a package from
the native arch, and that means it can only depend on a foreign-arch
package if that package is marked "Multi-Arch: foreign". See the
MultiArch spec[1].
You can solve your problem by building dynamips for amd64 from the
source package, or install the 0.2.7-0.2.8RC2-4 version from stable.
