[Insight-users] Installation problems!

It all depends on your preferences. As such there is no "right" path to 
install your binaries . The only thing we encourge new ITK users to do is
an out-of-source build . For example,  what you might want to do is 
store the source tree in
"/usr/local/src/Insight"

and build ITK in a separate directory, say for example

"/usr/local/bin/Insight_bin"

This scheme will keep things clean...

How are you building the examples????  Are you building  them as part of 
the full ITK build or separtely on individual basis?
If you are building the examples separately, you have to modify the  
CMakelist file a bit, you can't just copy and use the one in  
Insight/Examples and build it.
