TEST5 : ./TEST_csh.csh Unknown Variable Error

[firat]

Hello Dear Users,

Before installing WRF ı have a problem in System Environment Tests part on test 5 ‘./TEST_csh.csh’ . when ı make this test 5 ı have the error 'Unknown variable modifier’

I checked that ı installed the newest version of csh and ı couldn’t find how ı can fix this problem. And is this a big problem which can block the installing ?

If you can help me, ı would be so much thankful

Thank you so much
