It's likely that the problem is just a missing swig include directory. Like
gcc, you can tell swig other directories to look into for header and
interface files. We set these up in GNU Radio using the
SET(GR_SWIG_INCLUDE_DIRS) variable and passing it information about the
location of the .i files for the required components.
My guess is that your gnuradio is installed into a "non-standard"
directory, that is, one that swig doesn't look for by default, and that
gr-baz isn't finding it and/or isn't passing the directory to swig. You'll
find the gnuradio.i file in $prefix/include/gnuradio/swig, where $prefix is
whatever directory you installed GNU Radio into, like /usr or /usr/local.
This isn't exactly a fix for your problem; I'd have to look at gr-baz to
figure out why it's not using it, but hopefully it's enough info for you to
work off of.
