Hi Kurt,

After you compiled, did you do a 'make install' before running your
code? It may be loading an 'old' version of the LibUtilities library
elsewhere on your system, rather the one with your std::complex template
instantiation.

You could look at 'otool -L <your-executable>' to see which libraries it
is actually choosing to load.

Cheers,
Chris
