Comment (by kimi4896171@…):

 I tried activating grads @2.0.2_7 and it works. But it occurred error like


 Error opening stroke character data set
   Data set names = /usr/local/lib/grads/scripts/font0.dat ; font0.dat}}}

 So i uninstalled all ports, reinstalled Macports and done self updating
 but it still occurs


 Error opening stroke character data set
   Data set names = /usr/local/lib/grads/scripts/font0.dat ; font0.dat}}}

 I think installing Macport hasn't any problem but installing grads has
 problem cause it showed


 $ sudo port install grads
 --->  Computing dependencies for grads
 --->  Cleaning grads
 --->  Updating database of binaries
 --->  Scanning binaries for linking errors
 --->  No broken files found.


 What should i do? i googled it but can't find answer what i want..
