postfix-current spewing out warnings while building

[Jakob Breivik Grimstveit]

mail/postfix-current behaves somewhat strange while building, is it
anything I should correct?



$ sudo make clean
make: "/usr/ports/mail/postfix-current/Makefile" line 92: warning: Couldn't
read shell's output for "/usr/bin/grep -m 1 '^purgestat'
/etc/mail/mailer.conf || true"
make[1]: "/usr/ports/mail/postfix-current/Makefile" line 92: warning:
Couldn't read shell's output for "/usr/bin/grep -m 1 '^purgestat'
/etc/mail/mailer.conf || true"
===>  Cleaning for postfix-current-base-2.11.20131001,4
make[1]: "/usr/ports/mail/postfix-current/Makefile" line 92: warning:

/etc/mail/mailer.conf || true"

[...]

And while building, I get a bunch (probably thousands) of these:

duplex_pipe.c:8:1: warning: '/*' within block comment [-Wcomment]
/*

duplex_pipe.c:9:1: warning: '/*' within block comment [-Wcomment]
/*      int     duplex_pipe(fds)

/*      int     *fds;

[...]

Thank you in advance.
