In the process of installing a new system, I noticed that sparc was not included in the KEYWORDS for app-text/gv. It works fine for me, and I use it several times a day (I spend a lot of time generating/reading/printing postscript files.) Indeed, I have used it for quite a while on sparc Solaris & Linux of various flavors with no particular problems.
Verified. Added sparc to keywords. Thanks for the heads up
