r442- Unrecognised URL scheme for default!

Following the instructions from:
        http://subversion.tigris.org/
I encountered the following problem when giving subversion my first spin.

Symptoms: Checking out the latest Source does not work as documented.

subversion-r442/subversion/clients/cmdline/svn co http://svn.collab.net/repos/svn/trunk/ -d subversion

svn_error: #21068 : <Bad URL passed to RA layer>
  Unrecognized URL scheme: http://svn.collab.net/repos/svn/trunk

from config.log:
$ ./configure

## ---------- ##
## Platform. ##
## ---------- ##

hostname = albunea.hq
uname -m = ppc
uname -r = 2.4.4-pre6
uname -s = Linux
uname -v = #4 Thu Apr 26 11:08:24 CEST 2001

Reading specs from /usr/lib/gcc-lib/ppc-redhat-linux/2.95.3/specs
gcc version 2.95.3 20001130 (prerelease/franzo/20001204)

configure:9776: WARNING: we have configured for a client-only build

It complies nicely.
I can say "make check" which irritated me as
I only have python1.5.2 installed and got no warning.
According to the INSTALL file I would have needed python 2.1 at least.

The following tests all ran fine:
 stringtest
 hashdump-test
 path-test
 random-test
 svn-test2.sh
 svn-test.sh
 target-test.sh

I have no idea which kind of bug it is.
It might as well be a documentation or configuration bug.

Best,
