Perl_pad_sv is in there.  How did you install 5.10.1?

phred@harpua ~/perl-5.10.1 $ ack Perl_pad_sv
embed.h
638:#define pad_sv                      Perl_pad_sv
2958:#define pad_sv(a)          Perl_pad_sv(aTHX_ a)

makedef.pl
627:                Perl_pad_sv

pad.c
927:Perl_pad_sv(pTHX_ PADOFFSET po)

proto.h
2386:PERL_CALLCONV SV*  Perl_pad_sv(pTHX_ PADOFFSET po);
