hylafax 설정 질문

faxsetup -server로 설정할라고 하는데요.
처음에 설정이 됐는데...
설정이 잘못되서 다시 설정할라고 했더니 아래와 같은 메시지가 뜨면서
설정이 안되네요....,ㅡ.ㅡ

Warning: /bin/egetty does not exist or is not an executable program!

The file:

/bin/egetty

does not exist or this file is not an executable program. The
HylaFAX software optionally uses this program and the fact that
it does not exist on the system is not a fatal error. If the
program resides in a different location and you do not want to
install a symbolic link for /bin/egetty that points to your program
then you must reconfigure and rebuild HylaFAX from source code.

FATAL ERROR: /usr/lib/sendmail does not exist or is not an executable program!

The file:

/usr/lib/sendmail

does not exist or this file is not an executable program. The HylaFAX
software expects this program to exist and be in this location. If the
program resides in a different location then you must either reconfigure
and rebuild HylaFAX or override the default pathnames in the distributed
software through one of the HylaFAX configuration files (consult the
HylaFAX documentation).

이거 어떻게 해결해야하는지... 아시는 분 답변 부탁드립니다...ㅠㅠ
그리고 아래와 같은 상황이라면

]#dmesg |grep ttyS
serial8250: ttyS3 at I/O 0x2e8 (irq = 6) is a 16550A
