GsTsExternalSessions computes the FFI calls for the GciTsLibrary on demand, using cpp to parse gcits.hf. This required cpp, and the gcc/g++ compilation environment; if this is not installed, it reports an error such as:
/usr/bin/cpp not found, package cpp must be installed on host running the gem or topaz -l process
This requirement applies when using GsTsExternalSessions in production environments, as well as development.
Install cpp/gcc/g++
