That's enough to convince me that something has changed.

Adding -fPIC to your VTK build won't help, the compile error is
complaining that python was built without -fPIC.  The typical way to
build python with -fPIC is to use "--enable-shared" when you build
python, because --enable-shared add the -fPIC flag by default.
