I've never used Vidalia on linux, why do you need it!?!?
Anyway, looks like libcrypto.so and libssl.so are in... "openssl" , dunno if they work with Vidalia
yum install openssl
if that error still there... try to cheat... at your risk:
ln -s ./libcrypto.so.0.9.8g ./libcrypto.so.4
ln -s ./libssl.so.0.9.8g ./libssl.so.4
