Mae govannon!
     Well,this has nearly been solved by recross-compiling the openssl
statically and building libssl/libcrpt.a into libspicec, but I still cannot
use the system ones, never mind.
*root at gnollwood:/angmar/gtk/spice-gtk-0.5/gtk# l libspicec.so snappy
-rwxr-xr-x 1 root root 5.6M 2011-03-31 15:54 libspicec.so
-rwxr-xr-x 1 root root  62K 2011-03-31 15:54 snappy
now the libspicec has "NO" dependences at all!
    Namaarie!
