Not sure if this is the best tack, but the below patch seems
to do the trick. What was happening was eval would barf when
it got the unquoted /foo/bar. Wrap the string in ""'s and
the error goes away. This snippet illustrates the problem:

$ perl -e 'eval "\"/foo/bar\"";'
$ perl -e 'eval "/foo/bar";'
Bareword found where operator expected at (eval 1) line 1,
near "/foo/bar"
        (Missing operator before bar?)
