[plt-scheme] a bug?

Hello plt-scheme,

Welcome to DrScheme, version 299.24-cvs13dec2004.
Language: Textual (MzScheme, includes R5RS).
> (require (lib "plot.ss" "plot"))
ffi-obj: couldn't get "do_fit" from "C:\\Program Files\\PLT-299.24\\collects/plot/compiled\\native\\win32\\i386\\libfit.dll" (???????????????; errno=127)

And on Linux, an relatively old version (version 299.24-cvs04dec2004), the
DrScheme quits abnormally with the input:
> (require (lib "plot.ss" "plot"))
> (plot (line (lambda (x) x)))
 

Best regards,
