I found one mistake again. I send the info, and new patches.


6) typo

| 5) TeXLive may have Ghostscript in /texlive/YYYY/tlpkg/tlgs, but
| search target file "gs_init.ps" may not be in it.

The name "landscape.ps" should be "landscap.ps".  


7) absolute path for Win

8) output of config/config.pl for pnmcrop and ppmtogif

At doing configure script, outputs for pnmcrop and ppmtogif are: 

  ...
  checking for pnmcrop... /usr/local/bin/pnmcrop

  /usr/local/bin/pnmcropyes
  ...
  checking for ppmtogif... /usr/local/bin/ppmtogif
  yes
  checking if ppmtogif can make interlaced GIFs... yes
  ...

but these lines are strange. The following patch may fix it.
