My end goal here is to successfully install a program called 'Gold Standard Drug Database'. We have provisioned a CentOS 6.4 (64-bit) server from rackspace to install this on (not quite sure why they got a 64-bit one). The original error that led to this was:

./GSDDUpdate: error while loading shared libraries: libssl.so.10: wrong ELF class: ELFCLASS64

After googling i determined that this was because we had 64-bit drivers.

I've tried a number of ways to do this, the latests was to download this source:
http://www.openssl.org/source/openssl-1.0.1e.tar.gz
and then run these commands:

(download and untar the source, then cd inside, then:

./Configure linux-generic32 --shared
make

on the make i got these errors (after pages of make logs?)

make[2]: Entering directory `/home/dcaley/openssl-1.0.1e/apps'
../libcrypto.so: undefined reference to `rc4_md5_enc'
../libcrypto.so: undefined reference to `mod_exp_512'
collect2: ld returned 1 exit status
make[2]: *** [link_app.gnu] Error 1

Did you try installing 32-bit versions of required libraries and exporting an appropriate LD_LIBRARY_PATH?

CentOS and other RPM distros are incredibly easy to run multilib setups. You're making this much more complicate than necessary.

Thanks to both of you, unfortunately (for my learning) my boss figured out how to do this last night apparently so i wont get a chance to try these suggestion. If i can get out of him what he did, i'll post it here for others to use.

Looks like it may have been a combination of the answers.

this is what he did to fix it

yum install glibc.i686
yum install libstdc++.i686
yum install openssl.i686

and something about sim-links that i didn't understand. hope this helps someone...

He installed the 32-bit versions. And it's symlink (as in "symbolic link" aka 'man ln').
