I did several rounds of test builds at the weekend on a fresh multilib 
VM, with highly repeatable results as follows:

1. a straight 64bit compile of pulse audio needed a compat32 version of 
json-c (I don't know why - just reporting results)

2. a 32bit compile also needed that compat32 version of json-c. It 
additionally needed compat32 versions of samba, fftw, libcap and GConf

A side issue is that in both 64 & 32bit compiles, speex wasn't detected 
despite being looked for in the configuration stage of the pulseaudio 
build. I see there's an update for speex in the latest SBo updates; I'll 
play with that this week.
