Running doit on sys-fs/btrfs-progs fails with the following error message:

[ERROR 18:36:40] Invalid version: 'rc1'

This autogen uses BeautifulSoup to go over a directory listing where the tarballs are uploaded when a new release is published. It then uses a series of string.split() operations to get the "version" portion from the tarball urls.

Apparently, this resulted in selecting "rc1" as the version portion of a tarball URL, which packaging.version will correctly consider invalid.

I think the problem is on on line 17:

vers.append( href.split(pkg_name)[1].split(".tar")[0].split("-")[-1])

Right now, this autogen is be locked to version "6.1.3" because the newest autogenerated ebuild is failling (see FL-11059), so right now it doesn't matter so much if the autogen fails. I caught this running merge-kits locally.
