That's not now the GPL2 works.  The GPL2 does not require the source code to be 
mirrored by us or even for it to be *easily* accessible or downloadable.  It 
just requires that we either distribute source, let users know how to request 
the source from us (with requester paying reasonable processing, shipping, and 
handling costs), or direct the requester to the upstream provider of the source 
code.  We currently satisfy this requirement with the third case (cf GPL2 3(c)) 
by listing the site in the Portfile.
