[plt-scheme] Error compiling plt-scheme 208

Hello. I'm the maintainer for mandrake linux plt-scheme package. I have 
troubles building latest version (208).

During make install stage:
setup-plt: Post-Installing MrEd
setup-plt: Done setting up
setup-plt:

It may be related to gcc version (3.4.1). However, previous version 
(207) build fine with exactly the same configuration.
