Hi, I am not a big expert on Crypt-SSLeay but I have used it a bit, I think that the main reason why it does not work when you package it and send it to other server is that SSLeay is hooked to your local OpenSSL installation, which is usually recompiled and built specifically for every server; you would have a lot of luck if your customers would happen to have their OpenSSL installations built exactly the same way that yours, it is very likely that some of them will not even have OpenSSL :-) I hope this helps.
