dovecot - May 2009 - compile error with patched dovecot-1.2.rc4

Hi,
I just downloaded the dovecot-1.2.rc4.tar.gz to do some tests.
I coud compile it and generate the package with no trouble on my Slackware 
12.2.0

Then as I wanted to try the patchs available at 
http://hg.dovecot.org/dovecot-1.2/#
I downloaded them and applied at once. When I tried to compile once again I 
got this error:

cmd-thread.o: In function `cmd_thread':
cmd-thread.c:(.text+0x219): undefined reference to `mail_thread_type_parse'
../../src/lib-storage/libstorage.a(mail-search-build.o): In function 
`search_arg_build':
mail-search-build.c:(.text+0x10b9): undefined reference to 
`mail_thread_type_parse'
collect2: ld returned 1 exit status
make[3]: *** [imap] Error 1
make[3]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src/imap'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/dovecot-1.2.rc4'
make: *** [all] Error 2

I removed the patched folder and untarred it again, but at this time I 
decided to apply
one patch at time just to see witch one gave me the trouble. When the first 
set of
patch ( http://hg.dovecot.org/dovecot-1.2/rev/d42a8623a008 ) was applied I 
got the same error.

Just to confirm it was this set of patch, I applied all the other set of 
patchs leaving that one
not applied and the compilation went out with no trouble.

As im not a expert so I am sending this report to the list in order to get 
it fixed.

Best Regards,
Carlos Xavier.

Makefile had changed. You need to run "autoreconf -i" and configure to
get it updated.
