Without seeing your sources I cannot say so much (and also I have
no experiance with these --wrap things). But one hint:

Have you carefully read the ld docs about this switch and have
you tried at first the example shown there?

What do you mean with "substituting in my source and some of
the libarries" ? As far as understand this switch of ld, you have
nothing to substitute, but only to provide your wrapper functions
and then link with the --wrap option.
