The problem appears to be effectively what Nicolas pointed out.  But the
reason for it is rather nefarious.  It is true 1.x versions of
libkst<foo>.so are installed in /usr/lib/ .  However, kst.pri contains

LIBS += -L$$OUTPUT_DIR/lib -L$$OUTPUT_DIR/plugin

I would have expected ld to find the libkst<foo> that was just built and
put in $$OUTPUT_DIR/lib before attempting to find one in the default path

However (this is the nefarious part), qmake appears to have prepended
(among other things) "-L/usr/X11R6/lib" to LIBS before the
-L$$OUTPUT_DIR/lib.  This is unfortunate since, in Slackware,
/usr/X11R6/lib is a symbolic link to /usr/lib, thus forcing ld to
consider system libraries first, before the local ones.

I'd argue qmake should only be inserting library paths that aren't
already in ld's default search path.  But I don't know why qmake's
developers wanted the X11 library directory searched first, so maybe
there's a reason?
