Bugzilla Bug 13022

After "emerge rsync" I tried to install curl, but it gives an error.
It's interesting that the path in the ebuild itself points correctly to an
.tar.bz2 file (so does the digest), while portage downloads an .tar.gz:

!!! Most likely a temporary problem. Try 'emerge rsync' again later.
!!! If you are certain of the authenticity of the file then you may type
!!! the following to generate a new digest:
!!!   ebuild /usr/portage/category/package/package-version.ebuild digest

this should fix it
rm /var/cache/edb/dep/net-ftp/curl*
