With a trunk build, I get a warning and the right svnversion output:
[[[

I'm not sure what causes this, but for reference here's the output of
'svn help propset' from trunk:
[[[
...
svn:externals - A newline separated list of module specifiers,
each of which consists of a URL and a relative directory path,
similar to the syntax of the 'svn checkout' command:
http://example.com/repos/zig foo/bar
A revision to check out can optionally be specified to pin the
external to a known revision:
-r25 http://example.com/repos/zig foo/bar
To unambiguously identify an element at a path which has been
deleted (possibly even deleted multiple times in its history),
an optional peg revision can be appended to the URL:
-r25 http://example.com/repos/zig@42 foo/bar
Relative URLs are indicated by starting the URL with one
of the following strings:
../ to the parent directory of the extracted external
^/ to the repository root
// to the scheme
/ to the server root
The ambiguous format 'relative_path relative_path' is taken as
'relative_url relative_path' with peg revision support.
Lines in externals definitions starting with the '#' character
are considered comments and are ignored.
Subversion 1.4 and earlier only support the following formats
where peg revisions can only be specified using a -r modifier
and where URLs cannot be relative:
foo http://example.com/repos/zig
foo/bar -r 1234 http://example.com/repos/zag
Use of these formats is discouraged. They should only be used if
interoperability with 1.4 clients is desired.
