[plt-scheme] SLIB3a4 and DrScheme 360

Hello,

I am attempting to use SLIB with DrScheme 360. I've downloaded the latest
SLIB version, which appears to be 3a4, and installed it as required in my
'collects' directory. I attempt to load it using either:

(require (lib "load.ss" "slibinit"))

or

(load (build-path (collection-path "slibinit") "init.ss"))

or by directly executing the definitions in the file "slibinit/init.ss"
which comes with DrScheme. Whatever the method, I receive the following
error:

..\..\slib\require.scm::6146: reference to undefined identifier:
slib:features

I am confident the routines are finding the slib library- when I move the
library I get a different error- but I don't know the cause or how to
address the problem that is giving me the error. I've inherited this problem
and am rather far afield; I'm not accustomed to Scheme programming. I
apologize if the resolution to this question is obvious to others.

Best, and thanks in advance,
John
