I'm having the exact problem! For few days now I'm trying to set an env with a 
pgpool and 2 db nodes. Everything works as expected except recovery. I also 
tried to compile from source Pgpool. Everything worked out in the end except 
when I tried to compile de sources from sql folder.

I'm using this repository for both Postgresql and Pgpool-II: 
http://yum.pgrpms.org/reporpms/repoview/letter_p.group.html

On all machines I have Centos 5.6 x64 as OS.

Is there any way to build a src.rpm package and then let the user just to 
rebuild it on his machine? I'm not an expert as well but I like the software and 
I want to implement it but I'm kinda stuck :(!
