RdbiPgSQL, OS X, and the location of libpq.5.dylib

This is really a PostgreSQL-on-MacOS question.  On a modern Unix- 
alike you tell ld.so about such paths via entries in /etc/ 
ld.so.conf.d, but then on all my systems libpq has been installed in  
standard places.

I think you need to ask on a MacOS list (e.g. r-sig-mac) if no MacOS  
guru answers here.

That's my next step, but the one thing that I'd like to check  
beforehand relates to:

dlopen(/Library/Frameworks/R.framework/Resources/library/RdbiPgSQL/ 
libs/i386/RdbiPgSQL.so, 6): Library not loaded: /usr/local/pgsql/ 
lib/libpq.5.dylib

Has RdbiPgSQL hardcoded the path to libpq such that the library must  
be in that location?

My understanding of Unix-alike dynamic loading isn't the best, but  
looking at the error my impression is that even if I do add a new  
location to DYLD_LIBRARY_PATH that the hardcoded path will be the only  
one searched.  This might again be a MacOS question, but I'm wondering  
if anyone has been able to use a prebuilt RdbiPgSQL binary with  
Postgres in a non-standard location?

Thanks!

Jason

P.S.  The symnlink solution is working, but doesn't feel as elegant as  
I'd like... but I am able to get things done.  Big thanks to the  
RdbiPgSQL developers for allowing me to avoid using ODBC!
