Comment (by sealinglip):

 I tried the second suggestion. After executed

 {{{
 sudo port install flex
 }}}
 , the problem is gone.

 Thanks a lot!

 > We have some prior reports of this error with other ports, including
 #55200, where the cause was never found, and #55152, where the user
 reported that they had Homebrew installed and uninstalling Homebrew solved
 the problem.

 > Do you have the MacPorts m4 port installed? The log shows /usr/bin/flex
 was used; this suggests to me that you do not have the MacPorts flex port
 installed, otherwise it would have been used. Try installing the flex port
 with `sudo port install flex`.
