Hmmm... boy, does it!

Turned out I just missed it. It's a symbolic link in /usr/local/lib
pointing to libgeos_c.so.1.1.1. But yesterday (to fix another problem) I
had to add /usr/local/lib to /etc/ld.so.conf.d/ld.so.conf. Then when I ran
ldconfig, I assumed that should take care of it. But you're right. I also
had to add and export LD_LIBRARY_PATH=/usr/local/lib. Anyway now it works,
thanks! Guess I better take a closer look at the configuration steps again.

Also very helpful, thank you!
