expect fails to build with tcl 8.5

[liontooth@…]

I was happy to see expect in macports, but it has a build problem on Leopard:

Assigning to maintainer.

Tcl 8.5.0 seems to have broken expect. I could install it fine until I upgraded Tcl. Not sure what the solution is right now.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #14771.

I experience the same error on Tiger.

FYI: Mac OS X already includes expect in /usr/bin/expect (though at least on Tiger it's the older version 5.42.0).
