Trouble building expect

I'm having some trouble building the expect port on current.  Any pointers
would be appreciated.

I received the following error building the expect port:

===>  Configuring for expect-5.38.0_1
configuring Expect 5.38.0
checking for autoconf... no
checking configure up to date... no
configure: warning: ./configure appears to be old (./configure.in and/or 
./Makef
ile.in are newer) and the autoconf program to fix this situation was not 
found.
 If you've no idea what this means, enter the command "touch 
./configure" and re
start ./configure.
===>  Building for expect-5.38.0_1

*** Error code 2

Stop in /usr/ports/lang/expect.
===>  Building for expect-5.38.0_1

I touched ./work/expect-5.38/configure, but continue to get the 
following error:
===>  Building for expect-5.38.0_1
make: cannot open Makefile.
*** Error code 2

Stop in /usr/ports/lang/expect.


Some specifics about my system:
