When linking against poco, get RegularExpression error

Question

I have tried building poco (poco-1.4.6p4) in several ways, all seem to build fine. However, when linking against it, all the different ways I have tried to build poco give error below. No matter what I choose, it appears that poco is being built with the clang++.

What is strange is that before I upgraded from Mountain Lion to Mavericks, none of this happened.

./configure --Darwin64 --shared

and

./configure --Darwin64-gcc --shared --no-tests

and

./configure --Darwin64-clang-libc++ --shared --no-tests

All the above seem to build fine.

But when I link against any of them, they all give the error below when linking against it.

Configure generally will pay attention to CC and CXX environment variables to allow you to change compilers the software will build with. Try and adjust these settings.
