Hmmm. I can't find a package named "openssl-dev" in Debian. What distro are
you using? How is the package called really?

As your includes are written above, the C compiler would look for a file
md5.h in the current compilation directory: most probably there isn't
one, since whatever package you installed will put it in a standard
system location, typically under /usr/include.

You can find that out by

  find /usr/include -name md5.h

Let's assume you get:

  /usr/include/openssl/md5.h

... then you'd have to tell your C compiler

  #include <openssl/md5.h>

(there are many other ways to steer that, like the -I command line
option, but let's start with this).
