I get this error when compiling any ebuild that uses einfo. Which is quite numerous and interupts my emerge world's. I have tried many different versions of portage with the last one being portage-2.0.32
run this quick bash script: `[ -a /sbin/functions.sh ] || emerge baselayout`
closing due to lack of user input and i'm pretty sure that it was just missing file ... it happens :x
