[Xymon] OpenSSL and OpenLDAP

[Trever Noggle]

I have been fighting this thing all night.  Trying to install xymon on 
Centos 7 inside of virtualbox.  openldap complains about openssl and 
openssl does not make it past the configure script.

Keeps getting this:

Checking for OpenSSL ...
Compiling with SSL library works OK
/bin/ld: cannot find -ltirpc
collect2: error: ld returned 1 exit status
make: *** [test-link] Error 1
Warning: Cannot link with SSL library
OpenSSL include- or library-files not found.
Although you can use Xymon without OpenSSL, you will not
be able to run network tests of SSL-enabled services, e.g. https.
So installing OpenSSL is recommended.
OpenSSL can be found at http://www.openssl.org/

If you have OpenSSL installed, use the "--sslinclude DIR" and "--ssllib DIR"
options to configure to specify where they are.

Continuing with SSL support disabled.

I have tried to use the packages from yum and tried to build them from 
scratch and nothing seems to work.  Any ideas?
