R devel - Sep 2009 - unable to load shared library (Symbol not found: _PQbackendPID)

I can't get the RPostgreSQL library to load on OSX and have no idea  
where it's going wrong...

 > library( RPostgreSQL )
Error in dyn.load(file, DLLpath = DLLpath, ...) :
   unable to load shared library '/Users/hamannj/Library/R/2.9/library/ 
RPostgreSQL/libs/i386/RPostgreSQL.so':
   dlopen(/Users/hamannj/Library/R/2.9/library/RPostgreSQL/libs/i386/ 
RPostgreSQL.so, 6): Symbol not found: _PQbackendPID
   Referenced from: /Users/hamannj/Library/R/2.9/library/RPostgreSQL/ 
libs/i386/RPostgreSQL.so
   Expected in: flat namespace
  in /Users/hamannj/Library/R/2.9/library/RPostgreSQL/libs/i386/ 
RPostgreSQL.so
Error: package/namespace load failed for 'RPostgreSQL'

I've used this on OSX before and have had to recently rebuild... does  
anyone know if an older archive works?

As you know, questions / complaints about contributed packages should go to
the maintainer first, i.e. me. Now, I do not have access to OS X -- but Neil
(CC'ed) kindly covers that angle.  Maybe the two of you can sort this out?

The current version works for other on OS X as far as I know.
