Thanks for both your replies.

Yes, I was silly not to "back up one dir" to Foo's dir and try it. It was almays my understanding the -I. puts . to the end of the @INC search path. But now I think not. It seems that -I. and -Mlib=. will both work for me, but for each the . is ordered differently: 

$ perl -I. -e 'print join("\n", @INC)'
