I need to connect using an http proxy and it does exist a repository that uses the http protocol. It is http://svn.savannah.gnu.org/svn/grub/trunk/grub2
So why to use svn:// that makes the ebuild fail when fetching if you are behind an http proxy?
At least check if $http_proxy is set and change the ESVN_REPO_URI consequently if you want to make something elegant.
svn:// is a lot more efficient than http:// and no one has complained

Problem solved. SVN died. And so did it's http official backup.
