# Attempt to work around a problem that affects libxml2 on 64-bits
# and probably breaks other things as well.  The issue stems from
# misuse of zlib by other libraries, but there's no other good place
# to put this fix.  Note to self - keep an eye on upstream for a
# proper fix.

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
