[plt-scheme] Error installing 352.8 (from source build)

Hi all,

Got an error installing 352.8 from source:
setup-plt: Installing Imperative Draw Teachpack
standard-module-name-resolver: expected argument of type <module
path>; given (lib "\u0000lass.ss")
setup-plt: Installing ProfessorJ
setup-plt: Post-Installing MrEd
setup-plt: Post-Installing MysterX
Warning: can't install MysterX on non-Windows machine
setup-plt: Post-Installing MzCOM
Warning: can't install MzCOM on non-Windows machine
setup-plt: Done setting up
setup-plt:
setup-plt: Error during General Install for Imperative Draw Teachpack
(/usr/local/lib/plt/collects/htdch/idraw)
setup-plt:   standard-module-name-resolver: expected argument of type
<module path>; given (lib "\u0000lass.ss")
make: *** [install] Error 1


Any ideas what this might be about?

Regards,
