It's relinking it with a different rpath - I think that is meaningless
on windows but it was the behaviour before I started hacking on libtool
for windows. The concept is to support running an application with the
built .libs not the installed ones, but still have the app run properly
when installed. Unless someone from libtool pipes up, I'll look into
this shortly. There is a configure option to tell libtool you will not
be running from the local directory: try configure --help
