That's not `even though', that's the reason.  You link with an unusual
library path,

> PNGLIB = -L$(PNGDIR) -L$(HOME)/usr/$(HOSTTYPE)/lib -lpng

 but (most probably) don't tell the runtime linker about
this path.

Try

   export LD_LIBRARY_PATH=$HOME/usr/$HOSTTYPE/lib

although, on non-linux systems the name of LD_LIBRARY_PATH may be
different, see man ld.so for details.
