It's not done by the *-devel rpms.  The pkgconfig hooks are in the
library rpms themselves (I just checked).

But that information is not required by ./configure, so what's
the point?
You don't need all those extra -lXXX flags; they will be pulled in
by the main shared library anyhow.

[2] ldd /usr/lib/libpango-1.0.so
        linux-gate.so.1 =>  (0xffffe000)
        libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0xb7f3b000)
        libgmodule-2.0.so.0 => /usr/lib/libgmodule-2.0.so.0 (0xb7f38000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7f34000)
        libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0xb7eae000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb7e89000)
        libc.so.6 => /lib/tls/libc.so.6 (0xb7d5b000)
        /lib/ld-linux.so.2 (0x80000000)

As I already said, the configure process works fine without this.
