I'm guessing they are generated in the 'make configure' step?
You can define a post-configure target, which gets run after make configure.
You could then patch them using sed or perl.

For example:

post-configure:
	${PERL} -pi -e "s@/usr/local@${PREFIX}@g" ${WRKSRC}/foo.h

or something like that. Note that this is hackish; however it should work.
Maybe other people have better solutions than this :)

It's not exactly a common situation...

That would be cool.
