I now ran into a second case which makes it very likely the xattr
support is indeed the problem. Trying to create a port for python
setuptools, calling "setup.py install" with debugging opened showed me
this error:

I then rebuilt python passing "ac_cv_header_sys_xattr_h=no" to its
configure script, so it thinks there is no sys/xattr.h header. Indeed,
this made the problem installing setuptools go away.

Cheers, Felix
