Update:

It seems that it is possible to let sourceforge pick the right mirror
automatically with wget

I used this:

wget
http://sourceforge.net/projects/boost/files/boost/1.49.0/boost_1_49_0.tar.bz2/download

and it produced something like this:

--2012-08-21 21:21:40--

etc....

So it seems that wget is able to pick mirror (garr in this case)
automatically.

So automatic sourceforge mirror selection should be trivial to do if all
the other sourceforge packages also follow the same syntax:
http://sourceforge.net/projects/${PACKAGE_NAME}/files/${PACKAGE_NAME}/${PACKAGE_VERSION}/${PACKAGE_FILENAME}/download
