Reason for this behavior is the current patch which should fix compilation issues in libplot/z_write.c against libpng 1.5.3 but also introduces this bug. Instead of just using png_jmpbuf (png_ptr) one must use setjmp (png_jmpbuf (png_ptr)).

Attached is a new "plotutils-2.6-setjmp-longjmp.patch" which replaces the old one (plotutils-2.6-libpng-1.5.patch).

Second attachement is "PKGBUILD.patch" and does the following to PKGBUILD:
- remove reference to and execution of "plotutils-2.6-libpng-1.5.patch"
- add reference to and execution of "plotutils-2.6-setjmp-longjmp.patch"
- increase pkgrel by 1 (to 3)
   plotutils-2.6-setjmp-longjmp.... (0.6 KiB)
   PKGBUILD.patch (1 KiB)
