Judging from the comment at the link you pointed to, this is a typical
problem for Linux-based OSes (and many other F/OSS operating systems):
the lack of ABI compatibility based on an implicit assumption that
the source code of all the components is available at any time and
hence *the distribution as a whole* can be made consistent when its
parts change their ABI.  The generic package provided by Process-One
probably tries to do its best in terms of compatibility but it can't
target all those myriads of Linux-based distros at once and therefore
can't provide 100% compatibiliy with any of them.  Distributing its own
pet build of openssl along that package on any system but Windows
is insane (ask the security team of your OS about why it is that).

There are several possible ways to solve this problem:
1) You have the source code--build ejabberd yourself and it will use
   the stock libraries of your OS.  Provided that they're not outdated
   (ejabberd does have requirements on the minimal version of Erlang
   runtime for instance) everything should work OK.
2) Stop trying to swim against the stream and use ejabberd package
   provided by your distro: its maintainer and testers made sure
   the package builds and works OK with the rest of the OS it targets.
   If your OS does not package ejabberd, you might as well consider
   changing the OS.
3) Buy support contract from Process-One or from someone else
   to make sure the combination of ejabberd and OS you need to
   be working is working.
