[plt-scheme] latest exp release problem

In order to get the latest (203.6-cvs14mar2003) drscheme to run 
(compile/install worked fine) I had to change line 75 in 
collects/algol60/tool.ss:

< (define/public (get-language-numbers (list 1000 10))

 > (define/public (get-language-numbers (list 1 10))

otherwise I get the run-time error:

add-language: language "Algol 60": expected number for "Experimental 
Languages" to be 1, got 1000

This is on RedHat 8.0, clean install.
