ELF interpreter /libexec/ld-elf32.so.1 not found

[TCIS List Acct]

I'm running 6.2-BETA2/amd64 and received the following error when trying to run 
a 32-bit app:

ELF interpreter /libexec/ld-elf32.so.1 not found

I've done a few mailing list searches and see talk relating to missing libs, but 
I don't know how to install/compile these libs on 6.2-BETA2.  Any pointers would 
be appreciated.

TIA.
