We don't have any packages for Mono 4.8 which are compatible with CentOS 
6, so you'll have to ask whomever supplied those packages about the 
specifics of the build.

mono-project.com 5.0+ packages are built without BTLS enabled on CentOS 
6, as it lacks a compiler which can compile the BTLS library.
