I get this: $ aclocal --dry-run /usr/share/aclocal/progsreiserfs.m4:13: warning: underquoted definition of AC_CHECK_LIBREISERFS /usr/share/aclocal/progsreiserfs.m4:13: run info '(automake)Extending aclocal' /usr/share/aclocal/progsreiserfs.m4:13: or see http://sources.redhat.com/automake/automake.html#Extending-aclocal Not sure if this is important enough to warrant opening a bug for it - seems to be upstream issue anyway, and does not affect the result of aclocal when using it in a PKGBUILD (didn't try building anything related to progsreiserfs though). This just makes makepkg output for some packages (namely kbd & klibc-kbd) not that pretty, :-P -- Roman Kyrylych (Роман Кирилич)
