And if you want more recent than version 1.4, either
switch to Buildroot 2011.11(-rc?) and use the hg methods for download
or
use the direct hg link to the tarball of the stable version 1.5 tag
that I posted.

The hg setup installed at SourceForge is set to provide a *.tar.bz2
of any tag in the repository, down to a specific file level.
Other hg repositories may be setup differently (the one I run provides
zip and *.tar.gz).

The Buildroot hg method will clone and tar-ball the entire repository,
which may take more than a few cpu cycles.  ;-)
But that is the more general method.

Hardcoding the URL displayed by the "tar-ball button(s)" when browsing
an hg repository leaves you with a strangely named file but it may
be a much smaller download.
Although not as general, that only needs the http methods available
in the older Buildroot versions.
