RedHat MultiNest: failed install, issue with CMake/BLAS/LAPACK (or pthreads) - installation

Question

I am trying to install MultiNest on my desktop running Enterprise Red Hat 6.6 (Santiago). I downloaded the necessary package (MultiNest_v3.9_CMake.tar.gz), and followed the installation instructions:
cd MultiNest/build
cmake ..
Although BLAS and LAPACK are installed, I get the following errors:
CMake Error at /usr/share/cmake/Modules/FindBLAS.cmake:594 (message):
A required library with BLAS API not found. Please specify library
location.
Call Stack (most recent call first):
/usr/share/cmake/Modules/FindLAPACK.cmake:142 (find_package)
src/CMakeLists.txt:31 (FIND_PACKAGE)
-- Configuring incomplete, errors occurred!

See also "/home/ianc/Downloads/MultiNest/build/CMakeFiles/CMakeError.log".
Any suggestions?
The output "CmakeError.log" is below, and seems to indicate that the problem instead involves something called "pthreads".
Determining if the pthread_create exist failed with the following output:

Answer 1

Install these libraries and their devel versions for the build headers
libblas{3,-dev} liblapack{3,-dev} libatlas{3-base,-dev} cmake build-essential gfortran
You can also try installing compat packages.

Answer 2

The error above indicates that the POSIX threading library, libpthreads, cannot be found on your system. This error originates from your system-provided FindLAPACK.cmake script rather than from something in the MultiNest package.
I don't know the specific library which provides this on RedHat, but you should be able to check using yum provides pthread. After this you can install it using yum install M where M is whatever library provides libpthread from the previous command.
