[racket] Trouble using make-base-eval

I filed this bug a few months ago:
http://bugs.racket-lang.org/query/?cmd=view%20audit-trail&database=default&pr=14066&return_url=http%3A%2F%2Fbugs.racket-lang.org%2Fquery%2F%3FResponsible%3Dstchang%3BState%3Dopen%3Bcolumns%3DCategory%3Bcolumns%3DSeverity%3Bcolumns%3DOriginator%3Bcolumns%3DSynopsis%3Bcmd%3Dsubmit%2520query%3Bsortby%3DNumber

I worked on a fix but was unable to come up with a satisfactory fix.
Here is the discussion:
