My guess is you now have both installed (maybe in different places) and 
it's finding the older one first. I don't know what package manager 
slackware uses (it had none when I last used it but that was a very long 
time ago). In Debian or Ubuntu, you can go into synaptic and see right 
away what version you have, but here's another way (I'm sure there must 
be better ways): Go into /usr/lib (or probably /usr/lib64 if you have a 
64-bit system) and do something like:

  find . -name 'libgnutls*' -print

In my case, that showed me that I'm getting it out of 
/usr/lib/i386-linux-gnu.
One of the files in there is libgnutls.a. So I did this:

  strings libgnutls.a | grep ^Version

That showed several lines, but the interesting one was:

  Version: OpenPrivacy 2.12.14%s

which agrees with what synaptic told me my version was. Do the same thing 
in /usr/local/lib (or /usr/local/lib64) and see if there's another one 
there. If you built 2.12.19 from source, that's probably where it is 
since /usr/local is normally the default prefix. Now, if you do have more 
than one version, maybe you can delete the older version (watch out for 
dependencies -- a package manager would help here). I don't know whether 
you can use LD_LIBRARY_PATH to tell configure where to look first, if you 
need to keep both versions.
