[Dovecot] Error Building v2.2

[Christian Wiese]

Hi Nick,

long time I haven't used RPMs or SRPMs, so I cannot really help about
it.

That there is no "reference of autogen" within the spec we shouldn't
really wondering about, maybe because this spec file is normally
used together with "release tarballs".

I fetched the nightly snapshot you are using to check the included
configure script, to see what version of autoconf was used to generate
it.

---------------------------snip--------------------------------------
#! /bin/sh
# Guess values for system-dependent variables and create Makefiles.
# Generated by GNU Autoconf 2.59 for Dovecot 20130326.
---------------------------snip--------------------------------------

As we see the included configure script was generate using autoconf
2.59.

Most probably the configure scripts of those version have been
generated with an autoconf version > 2.59.

Taking a quick look into the dovecot 2.1.12 sources reveals that the
included configure script was generated with autoconf 2.68.

---------------------------snip--------------------------------------
#! /bin/sh
# Guess values for system-dependent variables and create Makefiles.
# Generated by GNU Autoconf 2.68 for Dovecot 2.1.12.
---------------------------snip--------------------------------------

So I guess we have nailed down the problem ;)

I would suggest that you really try to tweak the spec file of that
package to regenerate the configure script. I have already seen that
there is no autogen.sh shipped within the nightly snapshots, so you
might want to try to call 'autorecon -vfi' _before_ calling 'configure'.
