Thanks for sending this.  We'll have to get a working Portland Group
compiler installed here to duplicate the problem before we can fix it,
if it's not a pgCC bug.  The C++ code seems to work OK with several
other C++ compilers, including g++ version 3.2.  In the meantime, can
you get by with CXX=g++?
