[plt-scheme] Error compiling from svn

I'm compiling from svn current (2524) on Freebsd.

I get the following error during setup

setup-plt: Done setting up
setup-plt: 
setup-plt: Error during Compiling .zos for PLAI (/usr/local/plt/collects/plai)
setup-plt:   private/datatype-core.ss:27:7: compile: unbound variable in module in: make-contract
install: Errors in compilation process! (1)

 === context ===
/usr/local/plt/./install:246:0: main

*** Error code 1

Stop in /usr/extra/plt/src.
*** Error code 1

Let me know if I can provide more details.
