Package libffi was not found in the pkg-config search path REDHAT6.5

Question

I am trying to run setup.py related to a proprietary software installation and it has dependencies on libffi.

Since its Redhat 6.5 the python version was 2.6 and i installed python 2.7.

libffi was already installed and when i create a virtualenv and try installing the software by running the setup.py i get the following error:

No package 'libffi' found
Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libffi' found
c/_cffi_backend.c:15:17: error: ffi.h: No such file or directory

My query is how do we modify the pkg-config search path. to point to libffi.pc?
