[Ipopt] Help!!! Make failure: Makefile: Must be a separator on line ...

[lqc234]

Hi everyone , hi Andreas!
   I used Ipopt on Tru64 system:alphaev68-dec-osf5.1b. I followed the instructions and the configure stage goes well, I even got "configure: Main configuration of Ipopt successful". However I encounted the mistakes in the "make" stage. In the end of the output ,it said : 

   Make: Makefile: Must be a separator on line 93. stop.
   ***Exit 1
   stop

I have checked the Makefile on line 93, it is :
  ACLOCAL = ${SHELL} /usr/users/df8002/gcclqc/Ipopt-3.6.1/missing --run aclocal-1.9
and I didn't find an error.
  The system uses ksh as its shell while I found that "The config.site file is a shell script forbin/sh and needs to conform to sh syntax." in https://projects.coin-or.org/BuildTools/wiki/user-configure#ConfigDotSiteFile. Maybe it is because the different shell program? I am not very familiar with the Make specifications. I attached the config.log and the Makefile generated. 
  Anyone can give suggestions? I am looking forward to the help! Thank you very much in advance!
