Make error: symbol lookup error: undefined symbol

Any help on this would be greatly appreciated. I am trying to install
1.9.3 on a RHEL Linux system that is pretty old. After running
./configure, I run ./make and get the error below.:
...
linking shared-object zlib.so
installing default zlib libraries
make[2]: Leaving directory `/opt/local/src/ruby-1.9.3-p0/ext/zlib'
make[2]: Entering directory `/opt/local/src/ruby-1.9.3-p0'
linking ruby
make[2]: Leaving directory `/opt/local/src/ruby-1.9.3-p0'
make[1]: Leaving directory `/opt/local/src/ruby-1.9.3-p0'

/opt/local/src/ruby-1.9.3-p0/.ext/i686-linux/enc/encdb.so: undefined
symbol: rb_encdb_declare
make: *** [rdoc] Error 127

Here is the top of the ./make output:

# make
        CC = gcc
        LD = ld
        LDSHARED = gcc -shared
        CFLAGS = -O3 -ggdb -Wall -Wno-unused-parameter -Wno-parentheses

        CPPFLAGS = -I. -I.ext/include/i686-linux -I./include -I.
        DLDFLAGS =

Thanks for your help. Please let me know how to get Ruby 1.9.3 up and
running.

A better idea would be to use [RVM](http://beginrescueend.com/rvm/).

Installing RVM as a single-user is easy (multi-user instructions can be
found on their site):

  1. Download `curl` and `git-core` from your package manager.

  2. Run the following command (super user permission not needed):
         $ bash -s stable < <(curl -ss \
           https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

  3. Load RVM into your bash file:
         $ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] \
           && . "$HOME/.rvm/scripts/rvm" >> ~/.bash_profile

  4. Reload your bash file by restarting the terminal or by running
     `source ~/.bashrc`.

  5. Test for rvm with `type rvm | head -1`. It should output `rvm is a
     function`.

Installing Ruby 1.9.3:

  1. Make sure all dependencies are met by running `rvm requirements`.

  2. Install Ruby 1.9.3 with `rvm install ruby-1.9.3-head`.

  3. Use Ruby 1.9.3 by running `rvm use ruby-1.9.3-head`. You can also
     set Ruby 1.9.3 to the default ruby installation by running `rvm use
     ruby-1.9.3-head --default`.

./ruby: symbol lookup error:

/opt/local/src/ruby-1.9.3-p0/.ext/i686-linux/enc/encdb.so: undefined

symbol: rb_encdb_declare

This is declared in:

encoding.c:void rb_encdb_declare(const char *name);
encoding.c:rb_encdb_declare(const char *name)

And in:

enc/encdb.c:void rb_encdb_declare(const char *name);
enc/encdb.c:#define ENC_DEFINE(name) rb_encdb_declare(name)

Other than that I have no idea why you get this error.

It would be helpful to provide accurate versions of make, gcc, glibc and
binutils as well.

Something like:

GCC Version: GCC version 4.6.1
Glibc Version: ldd (Debian EGLIBC 2.13-20) 2.13
CFLAGS in use: -fomit-frame-pointer -frerun-loop-opt -pipe -fPIC
-pthread
Binutils Version: GNU ld (GNU Binutils) 2.22
