if you inherit autotools and then call eautoreconf depending on a use flag, repoman says: no eauto* function called. A construct like the following triggered the warning: if use boinc; then ebegin "need boinc/config.h"\ && cd "${S}/boinc"\ && eautoreconf\ && cd "${S}"\ && eend || die "eautoreconf of boinc failed" fi
Thanks, this is fixed in svn r12260.
This is fixed in 2.1.6.2 and 2.2_rc18.
