Interesting.  This gave me reason to re-examine the root cause of these 
problems.  Turns out that (at least on this platform), the only change 
needed to get it to build was adding "-fno-exceptions" to the CXXFLAGS.

Now I'm stuck at the old "Could not connect to existing gnuplot_qt, 
starting a new one", and "Warning: slow font initialization" nuisance. 
But since that's the same between GCC and clang builds, I'll chalk that 
on up to Qt itself.

"Crashes" is rather a small amount of information.  Could you dig a 
little deeper, preferrably using the debugger?
