[Dovecot] Building Pigeonhole

[Peter Bell]

I'm attempting to build Pigeonhole 0.2.3 for use with my Dovecot 2.0.12 
installation on Slackware.

I've downloaded the sources and unzipped into a folder which sits 
alongside the folder in which I built Dovecot.

When I ./configure, the configuration appears to complete without error. 
  However, when I make, the compiler throws lots of errors all stemming, 
I believe from its failure to find a set of include files:

cmd-vacation.c:4:17: error: lib.h: No such file or directory
cmd-vacation.c:5:17: error: str.h: No such file or directory
cmd-vacation.c:6:22: error: strfuncs.h: No such file or directory
cmd-vacation.c:7:17: error: md5.h: No such file or directory
cmd-vacation.c:8:21: error: hostpid.h: No such file or directory
cmd-vacation.c:9:26: error: str-sanitize.h: No such file or directory
cmd-vacation.c:10:29: error: message-address.h: No such file or directory
cmd-vacation.c:11:26: error: message-date.h: No such file or directory
cmd-vacation.c:12:20: error: ioloop.h: No such file or directory

I believe that these files are all part of the main Dovecot - what am I 
meant to be doing so that the Pigeonhole build process can find them?

Peter.
