There's a bug in the application's "configure" script that prevents
it from detecting the presence of installed png/jpeg libraries.

	... configure output ...
	checking png.h usability... yes
	checking png.h presence... yes
	checking for png.h... yes
	checking for png_read_info in -lpng... no
	no libpng installed; building static version
	checking jpeglib.h usability... yes
	checking jpeglib.h presence... yes
	checking for jpeglib.h... yes
	checking for jpeg_start_decompress in -ljpeg... no
	no libjpeg installed; building static version
	...

So this change is a no-op and only has documentation value at this
point of time.

This bug needs to be tracked down and fixed & fed upstream.

In the meantime, I'm working on the assumption that the PLT group
tracks critical fixes to the 3rd-party code that they are redistributing.
