automake (automake-1.8) ругается на libmcrypt.m4: detected automake-1.8 /usr/share/aclocal/libmcrypt.m4:17: warning: underquoted definition of AM_PATH_LIBMCRYPT run info '(automake)Extending aclocal'
Баг лечится правкой строки c: AC_DEFUN(AM_PATH_LIBMCRYPT, на AC_DEFUN([AM_PATH_LIBMCRYPT],
apparently wontfix (probably fixed in sisyphus, 4.0?)
