Comment (by zzanderr):

 Tried to autoupdate configure.ac and got:


 {{{
 $ sudo autoupdate configure.ac
 aclocal.m4:17: warning: this file was generated for autoconf 2.69.
 You have another version of autoconf.  It may work, but is not guaranteed
 to.
 If you have problems, you may need to regenerate the build system
 entirely.
 To do so, use the procedure documented by the package, typically
 'autoreconf'.
 }}}

 Note: I am not at all sure if I did this correctly (i.e., I don't know
 what I'm doing).  Just thought I'd throw it in if it helps.
