[Boost-users] How do I build boost with a specific compiler flag?

Hello, I am developing a C++ application on a Linux (CentOS 6.6) platform with gcc 4.8.2. I need to build the Boost libraries I'm using (Regex and others) such that the code is compiled with the "-fPIC" (position-independent code) option. I looked around on the Boost web site and found information about a configure script and something called Boost.Config. I quickly got overwhelmed. What do I need to do to have the Boost build system use this flag to build its libraries? Is it something fairly simple, or do I need to invoke a complicated set of steps?
