I put them in /usr/local/lib.  After you move them there, run 'ldconfig'
as root.  Worked fine for me.   I don't remember what the source tree
was like for libusb, but a lot of source packages have a 'make install'
option, too, which will copy all of the files to the correct places, and
give them the right permissions.

Also, Debian has gphoto2 and libusb packages available, so I am sure
that RPM based distros do, too.  That is pretty easy.

One last note, setting up dynamic USB devices, that aren't given a
permanent place in the /dev directory, for non-root users can be a
real pain.  You have to supply scripts to hotplug or usbmgr to get it
to work.  It was easiest for me just to change the binary to setuid
root, with chmod ug+s /path/to/gphoto2.  That has security implications
if gphoto2 were found to have bugs, but they are fairly minor on a
single user type box.
