[plt-scheme] How to invoke errortrace with MzScheme v4.1?

I would like to invoke MzScheme v4.1 with errortrace, a la 

>MzScheme.exe -M errortrace

as was possible in v372, but for some reason, according to the help
provided by 

>MzScheme.exe -h

the -M option, which used to be mapped to 

>-e '(require (lib "<coll>.ss" "<coll>"))'

no longer exists.

So, I tried running

>MzScheme.exe -e '(require (lib "<coll>.ss" "<coll>"))' errortrace

only to get the following error message:

>#f::1: read: expected a `)' to close `('

How do I invoke errortrace with MzScheme v4.1?
