It is enough to rename the ebuild and change the download url. For po4a is it
*not* enough to take the version number in, this is the correct download url to
use:
http://alioth.debian.org/frs/download.php/2108/po4a-0.32.tar.gz
The download urls do always vary by the 4 digit number before the actual
filename. There seems to be no clean sheme behind this so the complete name can
be enterd.
Just changing the downloadurl (and renaming the ebuild to 0.32) was enough for
me to build this package, should be a clean and easy version bump.
