I do not know the answer to this, but I would expect the system to find
the right library automatically. Perhaps there is some problem with the
way your openssl is installed. FWIW, this is what I find on my SuSE Linux
box:

-r-xr-xr-x 1 root root  355560 2012-01-11 12:04 /lib/libssl.so.1.0.0
-rwxr-xr-x 1 root root  248996 2011-12-20 16:15 /usr/lib/libssl3.so
-r-xr-xr-x 1 root root  319864 2010-12-09 06:17 /usr/lib/libssl.so.0.9.8
-r-xr-xr-x 1 root root  377504 2012-01-11 12:10 /lib64/libssl.so.1.0.0
-rwxr-xr-x 1 root root  254808 2011-12-20 15:58 /usr/lib64/libssl3.so
-rw-r--r-- 1 root root 3652164 2012-01-11 12:10 /usr/lib64/libssl.a
lrwxrwxrwx 1 root root      22 2012-08-06 20:40 /usr/lib64/libssl.so -> /lib64/libssl.so.1.0.0

But I should say that I have not actually tested the plugin myself, so
I can't say if this works with a 32-bit VM.
