GnuPG dependency on libreadline.so.6

[Tezmo]

I want to use GnuPG; I've pulled a plugin from slackware:

 

gnupg-1.4.20-x86_64-1.txz

 

when I come to execute gpg, I get the following error:

 

root@Stash:~# gpg
gpg: error while loading shared libraries: libreadline.so.6: cannot open shared object file: No such file or directory

 

Any ideas how I can get libreadline.so.6 installed so that gnupg can run? I see that libreadline.so.5.2 and libreadline.so.5 are baked in, but all variations of gnupg that I can find depend upon 6. All suggestions gratefully received!
