There is an issue on Boost.Thread regression test for PGI compiler. See 
https://svn.boost.org/trac/boost/ticket/6354.

"../boost/config/requires_threads.hpp", line 86: catastrophic error: #error
           directive: "Compiler threading support is not turned on.  Please

   #  error "Compiler threading support is not turned on.  Please consult your compiler's documentation for the appropriate options to use"

boost/config/compiler/pgi.hpp defines BOOST_HAS_PTHREADS but not 
BOOST_HAS_THREADS, resulting in failure in the requires_threads.hpp header.

It seems that adding

#define BOOST_HAS_THREADS

inboost/config/compiler/pgi.hpp solves the issue.

John, what do you think?

Could I add it?

Best,
Vicente
