IMHO this is one drawdack of EAPI 2 use dependencies. The ebuilds
needs a package with a particular use flag but some versions of said
package do not use this flag and portage gets in trouble. So this is
clearly a bug.
I am not sure but a fix would be something like this:
python? || ( >=dev-lang/swig-1.3.39 <dev-lang/swig-1.3.39[python] )
