Both is true. Unfortunately, at the moment setup.py uses the
c-extension kpathsea as the default. Then you need indeed some header
files and the kpathsea library. In the teTeX distribution,
they can be found in
    /<...>/teTeX/include
    /<...>/teTeX/lib
Whether they are included in TeXShop is unclear to me.

If they the files are present, you should create a file "setup.cfg" in
the directory where setup.py resides, with the following content:

    [build_ext]
    include_dirs=<Your-Tex-Path>/include
    library_dirs=<Your-Tex-Path>/lib

If this does not work, however, there is the fallback-solution that
uses the usual "kpsewhich" command which should be part of your
TeX-distribution. This tells PyX where the necessary TeX-files are.
In this case setup.py should not try to build the kpathsea extension.
Please remove the entry

    Extension("pyx.pykpathsea._pykpathsea",
              sources=["pyx/pykpathsea/pykpathsea.c"],
              libraries=["kpathsea"])

in setup.py.
Then, the command
    python setup.py install
should work fine.

Best greetings from Germany,

   Michael
