On my RedHat 8.0 system I am running exim & apache 2.0 with the default autoconf of 2.53-8.  

When issuing the ./buildconf, ./configure <insert zillion options here> configure does not find sendmail in the path given to it.  That is because of a bug in the autoconf 2.53 code base where AC_PROG_PATH does not properly search through non-expanded parameters passed to the search string.  ie.  
$PATH:/usr/sbin -> it will search through the properly expanded $PATH but will not search in /usr/sbin.  

As such I would like ot recommend this patch which should work with 2.13 & all versions of autoconf going forward.
