Bugzilla Bug 103051

procmail-3.22-r7 waits for input during build when no recognised mailer is
installed. It tries to autodetect the mailer, but if it cannot, rather than
using a default value, it asks the user.

Reproducible: Always
Steps to Reproduce:
1. emerge -C virtual/mta
2. emerge mail-mta/nbsmtp
3. emerge mail-filter/procmail
Actual Results:  
% sudo emerge procmail

Could not find any mailer.  It should be a mailer accepting at least
one plain destination address as its only argument (any sendmail
compatible mailer will do), and the mail-to-be-sent on stdin.
What is your mailer called?  (You can override this in config.h)
<wait for input>

Expected Results:  
Install without any prompts

From src/autoconf:

if _autotst 2 3 >>$ACONF
   test $? != 0 ||
    lookfor sendmail || lookfor smail || lookfor mail #|| lookfor rmail
then
:
else
 echo 'Could not find any mailer.  It should be a mailer accepting at least'
 echo 'one plain destination address as its only argument (any sendmail'
 echo 'compatible mailer will do), and the mail-to-be-sent on stdin.'
 echo 'What is your mailer called?  (You can override this in config.h)'
 read a
 echo "#define SENDMAIL \"$a\"" >>$ACONF
fi

nbsmtp satisfies procmail's virtual/mta dep, but does not provide a
send-/s-/mail script.

Simply hitting <Return> makes the build continue.

% emerge -pv procmail virtual/mta

These are the packages that I would merge, in order:

Oh, I'd almost forget:

Ok, this is similar to bug #102098. I committed nbsmtp-1.00-r2 to the tree
providing a real sendmail script and blocking virtual/mta.

(This was a nbsmtp issue rather than a procmail one)

Cheers,
