Bug#541536: apache2: need Build-Conflicts with autoconf2.13??
This package requires a Build-Conflicts: autoconf2.13 otherwise the
mkdir -p debian/build-tree/itk
[do patches then autoheaders, then...]
autoconf: Undefined macros:
configure.in:186: AC_MSG_NOTICE([Using external PCRE library from $PCRE_CONFIG])
configure.in:191: AC_MSG_NOTICE([Configuring PCRE regular expression library])
make: *** [mpm-itk] Error 1
Note that autoconf almost certainly ascertained that this was a
version 2.13 configure.in file, as it says AC_PREREQ(2.13).
Or maybe there was a different error?
