It seems the makefile was only looking at the first '-I' and not all of them

Possibly an issue with your quoting (or lack thereof).
When giving multiple '-I' args to Makefile.PL's INC, you need to enclose them in double quotes: 
perl Makefile.PL INC="-I/first/location -I/second/location"

But if there's only one '-I' then you can do away with the double quotes.

Cheers,
Rob
