My environment is as follows:
RHEL 6.7 Workstation
Qt v4.8.4
Qt Creator v2.8.1

When Creator built and installed many plugins failed to install because certain libraries could not be found that were needed by GLIBCXX_3.4.15
When queried the system reports GLIBC versions up to 3.4.13

Qt is now packaged with RHEL v6 and above. That is Qt v 4.6.2

What should I change to make this all play together.

Thanks for any help
