Hello! Well, thanks for your helpful and gentle hints

I created a new version today -- see my previous post. If you were interested as well, please try it and let me know how it goes.

I don't really know why '/usr/local' is so wrong, but I have tried to take your advise and deviated from the 'default' instructions provided in the source, and used the following to 'configure' the three parts of this (libgphoto2, gphoto2, libtool):

./configure --prefix=/usr

This appears to made everything relative to '/usr' instead of '/usr/local'.

P.S. I have no idea how populating some '/usr/local' directories could have any negative effect on your $PATH -- no one else reported such problems to me
