I've been looking into this for a while (all the try catch blocks in pkg don't make it much easy) and here's what I found thus far: * the reason why the error still occurs even when autoload is off is because pkg always loads the package at the end of an installation for a short while to generate a cache for documentation * removing the java package solves the problem sincee chk_spreadsheet_support never gets called that way (this took me a while to understand because I kept getting the same error even after removing the src/ directory) I don't understand why you only get the error when you run it as normal user and not as root, that kind of error doesn't validate my hypothesis of being a problem of using a function that is not loaded yet. It kind points to some problem with pkg prefix (or something that uses it). I have created a post_install script that removes the file and that solves the problem (I have hardcoded the path but I think it's possible to guess it with pkg). However, it seems to me that the best approach is to fix something in octave-core. Or maybe not. Maybe it doesn't make sense to have PKG_ADD calling a function that belongs to the package that is gonna be loaded.
