I think the problem there is the space in - e, which should be appearing as -e

Remove that space and at least one of your problems should go away.
However, I don't know exactly where to look in order to fix whatever it is that's inserting that space - somewhere in ExtUtils::MakeMaker, I guess.
What version of EU::MM do you have ?

Update: On closer inspection it seems that you might be responsible for the insertion of that space - as the space aint there in your first post.

Cheers,
