Log message:
lang/ruby34: Fix PRISM parser behavior on NetBSD

Fix segmentation fault when execute ruby binary without argument reported by \ 
ryoon@ and mef@.

prism/prism.c use "fgets" as functions's parameter and the parameter
is function pointer.  On NetBSD, fgets(3) was called instead of passed
function pointer.

So, replace "fgets" to other name.

Bump PKGREVISION.
