# This eclass patches ltmain.sh distributed with libtoolized packages with the
# relink and portage patch among others

INHERITED="${INHERITED} ${ECLASS}"

# 2004.09.25 rac
# i have verified that at least one package can use this eclass and
# build properly even without libtool installed yet, probably using
# the files in the distribution.  eliminating this dependency fixes
# bug 65209, which is a showstopper for people doing installs using
# stageballs <3.  if anybody decides to revert this, please attempt
# to find an alternate way of resolving that bug at the same time.
