From the GCC manpage:
The directories searched include several standard
system directories plus any that you specify with
`-L'.
Normally the files found this way are library
files--archive files whose members are object
files. The linker handles an archive file by scan-
ning through it for members which define symbols
that have so far been referenced but not defined.
However, if the linker finds an ordinary object
file rather than a library, the object file is
linked in the usual fashion. The only difference
between using an `-l' option and specifying a file
name is that `-l' surrounds library with `lib' and
`.a' and searches several directories.
hence either order should work, as well as:
-L/usr/local/lib/libparanoia.so
