qpopper compile failure

[David Southwell]

qpopper has been working fine (amd64 running postfix) but on portupgrade I am
Getting the following error:

set MISSING_OBJS to  base64.o 
set MISSING_SRCS to  base64.c 
Set AR_FLAG =  -r ; RANLIB_CMD = 
checking for sendmail program... ERROR: The sendmail program cannot be located
===>  Script "configure" failed unexpectedly.


sendmail is 
[root at dns1 /usr/ports/mail/qpopper]# whereis sendmail 
sendmail: /usr/local/sbin/sendmail /usr/local/man/man1/sendmail.1.gz 
/usr/src/usr.sbin/sendmail

qpopper config log includes the following lines:



PATH: /usr/local/kde4/bin

PATH: /usr/bin
PATH: /usr/games
PATH: /usr/local/sbin
PATH: /usr/local/share/lprof
PATH: /usr/local/bin
PATH: /home/admin/bin

Does anyone have any idea why this error might occur?
