When i whas installing and almost finished i had to build a custom kernel. I used the gentoo sources for this. In the menu config i added aic7xxx support for my adaptec 2940 scsi adapter. When i stared to compile it exited with with exit 1 and when i looked a few lines back it sayed i couldnt find the command "yacc". I issued the command (cd /usr/bin;ln -s yacc.bison yacc) and after that it compiled good. If yacc is not installed I think that bison should provide that symlink. Reproducible: Always Steps to Reproduce: 1. 2. 3.
if /usr/bin/yacc doesnt exist, a symlink will be created automagically
In mine PPC gentoo, instaklled from Stage3 there wasn't this link
