[gentoo-lisp] mit-scheme-c problems

[Nick]

Hi there,

I'm just learning Lisp, as I start to work through the Structure and 
Interpretation of Computer Programs book, and I'm having troubles 
getting the mit-scheme-c to be co-operative.

I rather suspect that the error lies with me being stupid, but I'd 
be everso grateful for a little help.

Essentially, whenever I try to load any scheme from a file into 
mit-scheme-c, it mis-reads it. A transcript will do well to 
illustrate:

-------------------------------------------------
echo '(define testvar 2)' | scheme
MIT/GNU Scheme running under GNU/Linux
Type `^C' (control-C) followed by `H' to obtain information about interrupts.

-------------------------------------------------

The same thing happens if I try to load a file, either using 
mit-scheme-c < testfile or mit-scheme-c --load testfile

This happens with both versions in the Lisp overlay, 20080130 and
20090107.

As I say, seems like it must be me being stupid, but I cannot see 
how.

Thanks alot,

Nick
