Hello Everyone,
I have just finished buting my workstation and wanted to get Nagios up and running which is actually OK. However, localhost cannot be monitored because I need to have the NRPE configured. When trying to install it:

checking for SSL headers... configure: error: Cannot find ssl headers

is all I get, I have verified that both openssl and libssl are installed. Can I get a little help on this one?

TIA!!
