vtk 3.1 problem with ./configure. Unix guru's please help!

[Bill Hoffman]

The problem is not the ldnet stuff, but rather this:

Your output says this:
checking whether the C++ compiler (g++  ) is a cross-compiler... yes
checking whether we are using GNU C++... yes


This means that configure was not able to compile AND run a small c++ program
using g++.   It was able to compile and link, but the run failed, so configure assumed that it was a cross-compiler.
