I doubt it. You're probably better off building libjpeg yourself.

Yes.

I think, by default, that it installs in /usr/local/lib. You can run 
configure --help in the libjpeg directory and it will give you a rundown 
of the various options, including where to install libjepg if you want a 
different place.

/usr/local is a good place to install stuff in a way that won't disrupt 
your system. OS X/Darwin puts its system stuff in /usr/bin, /usr/lib, 
and so on.
