 It looks a lot like the compiler has given up on a lot of C++11 support,
 which this package does require.
 
 It's possible to temporarily work around it by finding the last cmake
 which didn't require C++11 (2 years ago maybe), but the C++ world loves
 using C++11.
 
 It might be worth trying if OpenCSW offers newer compiler versions, or
 to discuss it up with them.
 
 A search on the Internet suggests the following will fail, too:
 
 #!/bin/sh
 
 cat << EOF > testc11.cxx
 #include <cmath>
 int main() { return 0; }
 EOF
 g++ -std=gnu++11 testc11.cxx
