So far we did not decide to deliberately break compatibility for older
Mac OS X versions with Tcl 8.4 only.

Mac OS X 10.5 Leopard only has Tcl 8.4. If I recall correctly, Tcl 8.5
was introduced with Mac OS X 10.6 Snow Leopard.

I started a wiki page to document which Mac OS X versions shipped which
version of Tcl:

  https://trac.macports.org/wiki/TclVersionInfo

That would make it easier to identify which versions would become
officially unsupported if we switched to Tcl 8.5, excluding the
possibility to ship an integrated Tcl installation with MacPorts itself.
