rails - postgres error: Reason: Incompatible library version: libpq.5.dylib requires version 1.0.0 or later,

Question

I am stuck with the setup of Ruby (1.9.3), Rails and Postgres (9.0.8) on my Mac (10.6.8). Everytime when I run rails console I get the following error:

Answer 1

Symlinking the files as above didn't work for me. pg would always look at libssl-0.9.8.dylib.

This question contains the right answer it seems: gem install pg --with-pg-config works, bundle fails

It boils down to

bundle config build.pg --with-pg-config=/Library/PostgreSQL/9.1/bin/pg_config

(or whichever pg you are targeting)

followed by gem uninstall pg and then bundle install
