by googeling R_INCLUDE_DIR I found that it is not recommended to rely on
${RHOME}/include
eg.

one way to get the include dirs
R CMD echo $R_INCLUDE_DIR
but the recommed way of finding the include dirs seems to be:
R CMD config --cppflags
on my system this returns
-I/usr/share/R/include -I/usr/share/R/include
but I can't use it with get_rconfig, since get_rconfig checks for -l/-L and
raises an ecxecption otherwise, more or less
If I hardcode the include dir in setup.py it finds the headers, but stops
with:
[EMAIL PROTECTED]:/usr/local/src/rpy_nextgen$ python setup.py install
running install

running build_py
