I'm having trouble with PDP finding some libraries. When I run ./configure I get:

checking for png_read_image in -lpng... no libpng not found: not building png support checking for XOpenDisplay in -lX11... no libX11 not found: not building X11 support checking for XvPutImage in -lXv... no libXv not found: not building pdp_xv checking for lqt_decode_video in -lquicktime... no libquicktime not found: not building pdp_qt checking for glXSwapBuffers in -lGL... no libGL not found: not building pdp_glx checking for SDL_Init in -lSDL... no libSDL not found: not building pdp_sdl target is linux

If I do locate on libGL and libXv I get:

/usr/X11R6/lib/tls/libGL.so.1.2 /usr/X11R6/lib/tls/libGL.so.1 /usr/X11R6/lib/libGLU.so.1 /usr/X11R6/lib/libGL.so.1 /usr/X11R6/lib/libGL.so.1.2 /usr/X11R6/lib/modules/extensions/libGLcore.a /usr/X11R6/lib/libGLU.so.1.3 /usr/lib/tls/libGL.so.1 /usr/lib/libGL.so.1 /usr/lib/libGLU.so.1 /usr/local/lib/libGL.so.1.2

and :

/usr/X11R6/lib/libXv.so.1 /usr/X11R6/lib/libXv.so.1.0

Any ideas why these libraries aren't being found??
