That is esentially the error: make[3]: Entering directory `/var/tmp/portage/pam-0.99.3.0/work/Linux-PAM-0.99.3.0/doc/specs' flex ./parse.lex ./padout < ./draft-morgan-pam.raw > draft-morgan-pam-current.txt /bin/sh: ./padout: No such file or directory Changing "emake" to "emake -j1" in the ebuild fixes the problem.

Azarah gave me the patch, fixed now. Thanks for reporting.
