Subject: Ruby-Postgres problems

All,

I'm having problems running the Ruby-Postgres extension, and am looking for 
any suggestions anyone may have:

After some initial trouble getting extconf.rb to find libpq, I suceeded 
creating the Makefile:

iusris@codedbliss[~/src/ruby-postgres-0.6.5] ruby extconf.rb
checking for cygwin32_socket() in -lwsock32... no
checking for socket() in -lsocket... no
checking for gethostbyname() in -linet... no
checking for gethostbyname() in -lnsl... yes
checking for sys/un.h... yes
checking for socket()... yes
checking for hsterror()... no
checking for gethostname()... yes
checking for PQsetdbLogin() in -lpq... yes
checking for PQsetClientEncoding()... yes
checking for pg_encoding_to_char()... no
creating Makefile

The rest of the process seems to work as well:
iusris@codedbliss[~/src/ruby-postgres-0.6.5] make
gcc -shared  -L/usr/lib/ruby/1.6/i686-linux-gnu -L/usr/lib  -o postgres.so  
-lpq -lnsl -lc

root@codedbliss[/home/iusris/src/ruby-postgres-0.6.5] make install
postgres.so -> /usr/lib/ruby/1.6/i686-linux-gnu/postgres.so
chmod 0555 /usr/lib/ruby/1.6/i686-linux-gnu/postgres.so

Then I noticed that there was very little to celebrate:

irb(main):001:0> require 'postgres'
LoadError: (null) - /usr/lib/ruby/1.6/i686-linux-gnu/postgres.so
        from (irb):1:in `require'
        from (irb):1

Checking ldd, I *think* everything is linking how it should be (according to 
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/24897):

root@codedbliss[/usr/local/pgsql/lib] ldd 
/usr/lib/ruby/1.6/i686-linux-gnu/postgres.so
        libpq.so.2 => /usr/local/pgsql/lib/libpq.so.2 (0x40013000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40023000)
        libc.so.6 => /lib/libc.so.6 (0x40039000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x4015e000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x4018b000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

.. so what's the LoadError caused by?

--- #My Configuration
- Postgresql-7.2.2
- Ruby 1.6.7 (2002-03-01) [i686-linux-gnu]
- Gentoo Linux

Many thanks to anyone, in advance, that can help me try to resolve this 
problem.
