This is a weird situation.  I'd say it is really a bug in how we built
the libtool support a long time ago.  We wanted automake to
automatically compute the -rpath argument for the user.  But this can
only be done if a library is only installed in one place.

One fix would be to have handle_ltlibraries look at the conditions
under which a library is defined.  If it is defined under multiple
conditions for different directories then we could simply omit the
`-rpath' computation.

A workaround for your case is something like this:

    lib_LTLIBRARIES = @LIBP_INST@
    noinst_LTLIBRARIES = @LIBP_NOINST@
    EXTRA_LTLIBRARIES = libp.la
    if P_SELECTED
    Clientdir = $(prefix)/include
    Client_HEADERS    = p.h 
    libp_la_SOURCES = events.c 
    libp_la_LDFLAGS = -rpath $(libdir)
    else
    noinst_LTLIBRARIES += libpl.la 
    libp_la_SOURCES = p.c 
    libpl_la_SOURCES = pl.c
    endif

The configure substitutions combined with EXTRA_LTLIBRARIES are enough
to fool automake into doing what you want.  (I haven't tested this.)
