According to http://bugs.gentoo.org/show_bug.cgi?id=239422 merging sys-apps/pcmciautils requires yacc (not just bison) installed.
I have bison installed and the /usr/bin/yacc --> /usr/bin/yacc.bison link created by the bison ebuild prevents sys-devel/yacc from merging. Does the following procedure sound safe? 1. quickpkg bison (in case of disaster) 2. rm /usr/bin/yacc 3. emerge yacc 4. emerge pcmciautils 5. emerge --unmerge yacc 6. emerge bison thanks, allan
