A problem with vtkImageReader...

[David Gobbi]

Hi Miguel,

I had this same problem with vtk2.3, but it was absent in
vtk2.4.  There are two solutions:

1) re-build VTK under RedHat-6.0 -- with vtk 2.3 you will 
   have to edit lex.yy.c and replace 
     FILE *yyin = {stdin}, *yyout = {stdout};
   with
     FILE *yyin, *yyout;

2) update to vtk2.4 if you haven't already -- or at least
   this worked for me.
