Did you run ./autogen.sh again?

I assume you have installed mercurial and are using the stable branch from the 
developers sources ? If so you might try deleting all contents that are not 
part of the archive (I occasionally have problems that this resolves).

        hg status | grep '^? ' | sed "s/^? /rm /g" | /bin/sh 

This will delete all files not part of the archive. If you do that, you'll have 
the start with "./autogen.sh".

If you still encounter the problem please attached a script of the commands you 
are running. For reference, I'm also using Macports, and am able to build with 
...

hg update -C
hg status | grep '^? ' | sed "s/^? /rm /g" | /bin/sh
./autogen.sh

make check

To make sure you have all the necessary dependencies, you can build the most 
recent octave port.

        sudo port build octave-devel +fltk+docs
