xsane-0.996 build log (0.997 fails the same way)

xsane fails to build against libpng-1.5, as it tries to access the jmpbuf member of the png_info struct.

The fix is easily patched with a simple sed one-liner in src_compile:

        ebegin "Patching ${S}/src/xsane-save.c for libpng-1.5"
        sed -i -e 's/png_ptr->jmpbuf/png_jmpbuf(png_ptr)/' \
                "${S}/src/xsane-save.c"
        eend $?

I'll attach an updated ebuild shortly.  I can confirm this fix works, at least for 0.997.  Should work for 0.996 too.
