problem installing shapelib

[Richard Nelson]

I'm trying to install xastir which has shapelib as a dependency. The  
installation stops with this:

--->  Configuring shapelib
Error: Target com.apple.configure returned: invalid command name "no"
Error: Status 1 encountered during processing.

I tried cleaning the port. I tried port sync. I tried port upgrade  
outdated. I've run out of ideas. Any suggestions? Thanks in advance.
