Can't install THC Hydra

[Joinix]

I know that many problems on installing THC Hydra has been posted, but i dont have the same problem.

When i have extracted the hydra-5.4-src.tar.gz folder, and CD'ed it.
I type "./configure" as you should do, nothing goes wrong.

But when i type "make" it says:



******@*******:~/Skrivbord/hydra-5.4-src$ make

Does anyone know whats wrong, and how i can fix it?

I have this same problem and I thought that it was just some libraries that hadn't been downloaded but am not sure. Anyone got anything helpful to add?



***EDIT***
It says that it cannot find the openssl directory but it is there. I have the latest version of openssl installed.
