From the full backtrace in your gist, this looks to be the same problem as <<issue 77>>. If the 'openssl' extension in the Ruby you're running is linked against a different version of OpenSSL than your PostgreSQL client library (libpq), and you load both of them, it can result in a segfault:

--1486-- /Users/kelly/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/i686-darwin11.1.0/openssl.bundle:
--1486-- dSYM directory is missing; consider using --dsymutil=yes
kdf> require_library_or_gem pg
--1486-- /Users/kelly/.rvm/gems/ruby-1.8.7-p352@jmn/gems/pg-0.11.0/lib/pg_ext.bundle:
--1486-- dSYM directory is missing; consider using --dsymutil=yes
vex amd64->IR: unhandled instruction bytes: 0xC8 0x88 0x0 0x0 0x66 0xF

The solution is to ensure that every dylib that links against OpenSSL is linked against the same version. I'm working on a way to detect this problem at runtime.

Duplicate of #77.

Thank you for the prompt reply and thank you for providing such good support.

I did the otool command as you described in the associated gist and got these results:
