Well, /something/ changed and the only thing I changed was KDE. So I'm 
trying to figure out why what worked before stopped working when I 
upgraded KDE.

I haven't touched gcc/libstdc++ since setting up my KDE4 environment.

$ which gcc
/usr/local/kde/gcc4/bin/gcc

Trust me, that's the compiler being used :-) (it's gcc 4.1.2 as 
previously indicated). The problem is that for some reason things aren't 
using the libstdc++ that goes with the gcc I'm using. Any ideas why?

I'm guessing what happened is that previously the system libstdc++ was 
"usable", and something changed in strigi that it suddenly needs the 
newer libstdc++.

Anyway I've worked around it for now by adding 
/usr/local/kde/gcc4/lib/gcc/i686-pc-linux-gnu/4.1.2 to my 
LD_LIBRARY_PATH, but I'm still confused as to *why* I need to do this.
