gsview-4.7 cannot open .ps files with ESP Ghostscript-8.15.2

[rkm]

I have a lfs 6.2 system that I built on my computer according to the lfs 6.2 book. The blfs development book says that either AFPL Ghostscript-8.53 or ESP Ghostscript-8.15.2 are required for Gsview-4.7. I originally installed ESP Ghostscript-8.15.2 because I understood from the book that it has support for CUPS, whereas AFPL Ghostscript-8.53 does not. However after installing gsview-4.7 I got the following error when trying to open a postscript file:

Found version 81502 Need version 704 - 919

I also noticed in the Gsview readme file that AFPL Ghostscript was specifically mentioned as a requirement. So I uninstalled ESP Ghostscript and installed AFPL Ghostscript instead, and I was able to open the same postscript file without any problems. I'm wondering if ESP Ghostscript should be removed from the list of prerequisites for gsview-4.7 in the book.

Indeed, the new versioning system of ESP Ghostscript breaks GSView. Even the newest 4.8 version.

However, I've found that simply substituting 81502 for 999 in the src/gvcver.h file allows GSView to work with newest ESP Ghostscript.

I'd like the community to decide on this approach, or simply change the dependency to AFPL only (by the way, AFPL Ghostscript is soon to be gone as the lead dev wants to go GPL).

I've tested the change, and all seems to work just fine.

Updated to GSview-4.8 and included a sed command in the instructions to accomodate recent versions of ESP Ghostscript.
