Alright, I found the reason for this, it
is related to Easy Install Stuff (still mea culpa).
At some point I must have followed
http://peak.telecommunity.com/DevCenter/EasyInstall#traditional-pythonpath-based-installation
which lead to a file
.pydistutils.cfg in my homedirectory with contents:

[install]
install_lib = ~/.PythonLibrary/Python$py_version_short/site-packages
prefix=~/.PythonLibrary/

#[easy_install]
#site-dirs=/usr/local/lib/pythonX.Y/site-packages

So it seems that this wins over a ``--prefix=<some_nice_path>``.
And this is ok, because:
"""
[...] you can use Distutils configuration files to record
personal or site preferences for any Distutils options. That is, any
option to any command can be stored in one of two or three (depending on
your platform) configuration files, which will be consulted before the
command-line is parsed. This means that configuration files will override
default values, and the command-line will in turn override configuration
files.
"""
http://docs.python.org/inst/config-syntax.html

Obviously, setting up a ~/.pydistutils.cfg is a good way
to cause trouble at some later time because it is easily forgotten.

The errors below persist...

Best, Arnd
