Are the Strawberry perl dirs at the front of the path? e.g., in my case the first three entries are:

PATH=C:\berrybrew\5.32.0_64\perl\site\bin;C:\berrybrew\5.32.0_64\perl\
+bin;C:\berrybrew\5.32.0_64\c\bin;

I wonder if something else is getting in the way? The Git for Windows MSYS shell has caused problems in the past, for example.
