The vsftpd ebuild lacked the ppc keyword. I edited the ebuild and compiled with no problems Reproducible: Always Steps to Reproduce: 1. emerge vsftpd Actual Results: missing keyword error Expected Results: compile and install :)
I suspect you mean ppc for the hardware here and not ppc64 ... but I did test build this on ppc64... seems a-ok .. commited as stable.
moving over to ppc
I added the ~ppc-Keyword to vsftpd 1.2.1
