Subject: 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'

./ruby: symbol lookup error:
/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

        XCFLAGS = -include ruby/config.h -include ruby/missing.h

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

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