I filed this bug report with macports: https://trac.macports.org/ticket/27937
The maintainer said he didn't know what was causing it and told me to contact the gv developers.
Here's the problem: I get this error at runtime with the latest compiled gv: sox.astro.psu.edu[122] Warning: translation table syntax error: Unknown keysym name: apLineDel Warning: ... found while parsing '<Key>apLineDel: GV_Page(page+5) ' Warning: String to TranslationTable conversion encountered errors As such, keybindings do not work anymore.
