8 # relink and portage patch among others

12 # i have verified that at least one package can use this eclass and
13 # build properly even without libtool installed yet, probably using
14 # the files in the distribution. eliminating this dependency fixes
15 # bug 65209, which is a showstopper for people doing installs using
16 # stageballs <3. if anybody decides to revert this, please attempt
17 # to find an alternate way of resolving that bug at the same time.
