[racket-dev] Pre-Release Checklist for v6.0, corrected url

> * Jon Rafkind <rafkind at cs.utah.edu>
>   Release tests for (one of the) linux releases:
>   - Test that the `racket' and `racket-textual' source releases
>     compile fine (note that they're still called `plt' and `mz' at
>     this stage).
>   - Test that the binary installers for both work, try each one in
>     both normal and unix-style installation modes. (just ubuntu)
>   [Note: get the release candidates from the URL in this email. Use
>    the 'static table' link to see a list of all tar files available]

done. tested 32 and 64 bit ubuntu versions and building from source for racket and minimal using the 'source' package. I did not test the 'source + pre-built packages' tar.
