You have to pass the correct --prefix to configure. The default is
/usr/local. With --prefix=/usr, the .pc files would go to

In general, you will have to expand PKG_CONFIG_PATH if the .pc files
are anywhere but /usr/lib/pkgconfig or /usr/share/pkgconfig. Also,
those two paths are automatically searched, so you don't need them in

There shouldn't be any bad side effects with installing outside of
/usr. That is the big thing that pkg-config provides. A package that
depends on another can easily find out about any additional flags
needed like -L/some/other/dir to build properly. Any rpaths would be
added by libtool, I think, and that's out of the hands of pkg-config.
